The magnitude of the velocity of the ball when it strikes the water below the bridge is 26.0 m/s.
This is calculated by using the equation v^2 = v0^2 + 2gh, where v0 is the initial velocity, g is the acceleration due to gravity, and h is the height of the bridge. In this case,
v_0 = 13.0 m/s, g = 9.8 m/s^2, and h = 24.0 m,
so the equation becomes:
v^2 = (13.0 m/s)^2 + 29.8 m/s^2*24.0 m = 884 m^2/s^2, and v = 29.7 m/s
To calculate velocity, you need to know the displacement and time. Velocity is the rate of change of displacement with respect to time, so the formula for calculating velocity is velocity = displacement/time.

a rock is dropped from a sea cliff and the sound of it striking the ocean is heard 4.0 s later. if the speed of sound is 340 m/s , how high is the cliff?
Speed: According to the problem the cliff is 680 m high
What is Speed?Speed is a measure of the rate at which an object or person moves. It is a scalar quantity, meaning it has only magnitude, not direction. Common units of speed include kilometres per hour (km/h), miles per hour (mph), metres per second (m/s), and feet per second (ft/s). Speed is related to velocity, which is a measure of the rate of change of an object's position. Speed is an important property of any moving object, and can be used to measure the motion of an object relative to another object.
The speed of sound is 340 m/s, which means that it takes 1 second for sound to travel 340 m. Since we know that the sound of the rock striking the ocean was heard 4.0 seconds after it was dropped, then the rock must have fallen for a distance of 4 times 340 m, or 1360 m.
To calculate the height of the cliff, we need to use the formula:
Height = Distance/2
Plugging in 1360 m for the distance, we get:
Height = 1360/2 = 680 m

A flasher generates 60° regular flashes in one minutes. Calculate (i) period of the flashes (ii) frequency of the flashing
(i) period of the flashes is, 1/60 minute/flash
(ii) frequency of the flashing is, 60 Hertz
What is frequency ?The frequency of a repeated event is the number of occurrences per unit of time. The common unit of expression is Hertz (Hz), which stands for cycles per second. For instance, a wave has a frequency of 1 Hz if it completes one cycle in one second. A wave moves faster and completes more cycles in a given period of time as its frequency increases.
Given that,
A flasher generates 60° regular flashes in one minutes
(i) The period of the flashes is the time it takes for one complete cycle of the flashing, or the time between two consecutive flashes. In this case, the flasher generates 60 flashes in one minute, so the period of each flash is given by:
Period = 1 minute / 60 flashes
= 1/60 minute
= 1/60 minute/flash
(ii) The frequency of the flashing is the number of flashes that occur in one unit of time, typically measured in Hertz (Hz), where 1 Hz = 1 cycle per second. To convert the period to frequency, we simply take the reciprocal of the period:
Frequency = 1 / Period

a friend incorrectly says that a body cannot be rotating when the net torque acting on it is zero. what is the correct statement?
The correct statement is that a body's rotation cannot change if the net torque acting on it is zero. This means that if there is no net torque acting on a body, its angular velocity will remain the same and it will not be able to rotate.
This is because when the net torque acting on a body is zero, the sum of all external torques is also zero. This means that the body's angular momentum is conserved, meaning that the body's angular velocity remains the same over time and it is unable to change its rotation. This can be demonstrated through Newton's second law of motion, which states that the rate of change of angular momentum is equal to the net torque acting on the body.

a 15g bullet it shot into a stationary 3 kg block that is hanging on a 45cm wire. if the bullet is shot at 380m/s and gets embedded in the block, then how high does the block swing?
The block swings to a height of approximately 2894 m.
The momentum of the system of bullet and block before the collision is equal to the momentum of the system after the collision. So conservation of momentum can be used in solving this problem.
Before the collision, the momentum of the bullet is:
p_bullet = m_bullet * v = 15 g * 380 m/s = 5700 g * m/s
After the collision, the momentum of the bullet and the block is:
p_total = m_block * v_block = (3 kg) * v_block
where v_block is the velocity of the block after the collision.
Using the conservation of momentum equation, we can find the velocity of the block:
5700 g * m/s = (3 kg) * v_block
v_block = 5700 g * m/s / (3 kg) = 1900 m/s
Now, we can use this velocity to find the height that the block swings. The height of the block swings can be found using the following equation:
h = (v_[tex]block^2[/tex]) / (2 * g)
where g is the acceleration due to gravity (9.8 [tex]m/s^2[/tex]).
[tex]h = (1900 m/s)^2 / (2 * 9.8 m/s^2) = 56875 m^2 / (19.6 m/s^2)[/tex] = 2894 m

About 3.2 TJ energy is liberated when two moles of 126C atoms are formed from their individual protons, neutrons and electrons.
The energy released when two moles of 126C atoms are formed from their individual protons, neutrons, and electrons can be calculated using the equation for nuclear binding energy:
[tex]B = Z * BE/A + (A - Z) * BE/A - m_n * c^2[/tex]
where Z is the number of protons, BE/A is the binding energy per nucleon, A is the total number of nucleons, m_n is the mass of a neutron, and c is the speed of light.
For carbon-12 (12C), the binding energy per nucleon is about 8.49 MeV, and for carbon-126 (126C), it's about 8.70 MeV.
The energy released when two moles of 126C atoms are formed can then be calculated as:

After a certain time interval, the magnitude of your displacement of the boat is 325 m. What is the time you travel for the northerly part of the trip? The velocity of the boat relative to the shore?
If you are in a speedboat which has a top speed of 22 m/s. the time you travel for the northerly part of the trip is 20.6 s. The velocity of the boat relative to the shore is: 18.5m/s.
How to find the velocity?The time for the northerly part of the trip can be calculated by using the equation for displacement:
displacement = velocity * time
Rearranging for time:
time = displacement / velocity
Plugging in the given values:
time = 325 m / 15.8 m/s = 20.6 s
To find the velocity of the boat relative to the shore, we need to find the total displacement of the boat and divide it by the total time.
The displacement in the westward direction is 22 m/s * 13.6 s = 304.2 m
The total displacement is the sum of the displacement in the two directions, so:
displacement = 304.2 m + 325 m
displacement = 629.2 m
The total time is the sum of the times for the two parts of the trip, so:
time = 13.6 s + 20.5 s
time = 34.2 s
The velocity of the boat relative to the shore can be calculated as:
velocity = displacement / time
velocity = 629.2 m / 34.2s

what do we need to know if we want to measure an object’s mass with newton’s version of kepler’s third law? explain.
To measure an object's mass using Newton's version of Kepler's third law, we need to know the object's distance from the center of a gravitational field and the time it takes to complete one orbit around that center.
Newton's version of Kepler's third law states that the square of the period of a planet's orbit (the time it takes to complete one orbit) is proportional to the cube of its average distance from the center of the gravitational field. Mathematically, this can be expressed as T^2 = k * r^3, where T is the period, k is a constant of proportionality, and r is the average distance from the center of the gravitational field.
To use this equation to measure an object's mass, we need to first determine the value of T and r for the object. This can be done by observing the object as it orbits around a known mass (such as a planet or a star) and measuring the time it takes to complete one orbit and the average distance from the center of the gravitational field.

Electric field = [tex]E=\frac{2K\lambda}{r}[/tex]
Where ,K=[tex]\frac{1}{4\pi \epsilon}[/tex]
[tex]\lambda[/tex]= charge per unit length
potential difference :
[tex]V_{2} -V_{1} =-{2K\lambda}ln\frac{r_{2} }{r_{1}}[/tex]
E = [tex]4(\frac{V}{M} )[/tex] = [tex]\frac{2K\lambda}{r_{1} }[/tex] at r=3
[tex]2K\lambda[/tex]=12V [tex]\rightarrow(1)[/tex]
[tex]V_{2} -V_{1} =-{2K\lambda}ln\frac{r_{2} }{r_{1}}[/tex]= -24
From (1)
24=-12[tex]ln\frac{r_{2} }{r_{1}}[/tex]
[tex]ln\frac{r_{2} }{r_{1}}[/tex]=-2
[tex]\frac{r_{2} }{r_{1}}[/tex]=[tex]e^-2[/tex]
[tex]r_{2} =r_{1}e^-2[/tex]
Electric field at [tex]r_{2}[/tex] = [tex]\frac{2K\lambda}{r_{2} }[/tex]
[tex]\frac{12}{r_{1}e^-2 } =\frac{12e^2}{3}[/tex]
E=[tex]4e^2[/tex]=29.55 V/m

a bicycle and a truck have the same momentum p. they experience the same stopping force f. which one stops first?
The answer depends on the amount of friction between the bicycle and the ground, and the amount of friction between the truck and the ground.
If the friction between the bicycle and the ground is greater than the friction between the truck and the ground, then the bicycle would stop first. On the other hand, if the friction between the truck and the ground is greater than the friction between the bicycle and the ground, then the truck would stop first. Additionally, the mass of the bicycle and truck would also play a role in which one stops first.
If the bicycle has a greater mass than the truck, for example, then the bicycle would take longer to stop due to its greater inertia. Therefore, the answer to which one stops first depends on many factors.
