The length of the first rough patch is 3.75 m.
The first rough patch is located at the point where the cart hits the spring of rest. The distance to this point is equal to the length of the spring (1.85 meters) plus 0.47 meters, which is 1.80 meters.
The cart's velocity after passing the first rough patch is 2 m/s, and the coefficient of kinetic friction is 0.47, so when it hits a spring of rest length 1.85 m (length of the second rough patch), it must have a velocity of 6.4 m/s in order to stop at a distance of 0.85 m from the spring.
This means that if height of the curved track is 4 m, then the length of the first rough patch is 3.75 m.

how does the distance traveled by the bullet compare with the distance traveled by the rifle in the same time, and why?
The comparison between the distance traveled by the bullet compared with the distance traveled by the rifle at the same time shows that the bullet travels faster than the rifle due to greater acceleration.
Newtown's third law of motion states that for every action there is a reaction having equal magnitude but opposite direction.
In the case of bullet and rifle, both experience the same amount of force that is equal in magnitude but opposite in direction.
In physics, mass and acceleration have an indirect relation with each other i.e a = F/m. More mass means less acceleration and vice versa.
A rifle has a smaller amount of acceleration than a bullet. It is because the mass of the rifle is greater than the bullet therefore it covers less distance a s compare to a bullet having less mass and greater acceleration and thus travels faster.

The proportionality dependence of the current (i) through any conductor to the voltage (v) across it and its resistance (r) is true for all conductors regardless of temperature.
a. True
b. False
It is FALSE that the proportionality dependence of the current (i) through any conductor to the voltage (v) across it and its resistance (r) is true for all conductors regardless of temperature.
When the conductors have a higher temperature, the molecules in the conductor will be more crowded and the result is the resistance of the conductor will rise. Hence, the current flowing through the conductor will decrease in the same voltage.
In the lower temperature, the resistance of the conductor will decrease and lead to more current flowing through the conductor in the same voltage.
Thus, the conductor temperature has an effect on its resistance.

a ball of mass 0.285 kgkg that is moving with a speed of 5.8 m/sm/s collides head-on and elastically with another ball initially at rest. immediately after the collision, the incoming ball bounces backward with a speed of 3.5 m/sm/s .
The velocity of the target ball after the collision is 1.4 m/s and the the mass of the target ball is 1.832 kg.
Define the terms velocity and mass.
By taking into account how long it takes the body to move, we may relate these three using the concept of velocity, which always ensures that the body is in motion. Since mass is a constant quantity, it has no effect on the body's velocity, yet a body in motion has kinetic energy. The kinetic energy is proportional to both velocity and mass.
Let us consider m1 and m2, v'1 and v'2 be the initial masses and velocities respectively and m1 and m2, v1 and v2 be the masses and velocities after Collison.
By law of conservation of momentum,
m1v'1+m2v'2 + m1v1+m2v2
Substitute the known values,
v'1 = 5.2 m/s
v1 = 3.8 m/s
v'2 = 0
Therefore,
0.285×5.2+0 = 0.285×(-3.8)+m2v2
1.482+1.083 = m2v2
m2v2 = 2.565 kg m/s (1)
Inelastic collision kinetic energy of the system is conserved.
1/2 m1v'1^2+1/2 m2v'2^2 = 1/2 m1v1^2+1/2 m2v2^2
m1v'1^2+m2v'2^2 = m1v1^2+m2v2^2
0.285×(5.2)^2+ m2×0^2 = 0.285×(-3.8)^2+m2v2^2
7.7064+0 = 4.1154+m2v2^2
m2v2^2 = 7.7064 - 4.1154
m2v2^2 = 3.591 (2)
From equation (1) and (2)
m2v2 = 2.565 kg m/s
(m2v2)v2 = 3.591
(2.565)v2 = 3.591
v2 = 3.591/2.565 = 1.4 m/s
and
m2v2 =2.565 m/s
m2(1.4) = 2.565
m2 = 2.565/1.4 kg
m2 = 1.832 kg
Therefore, the velocity of the target ball after the collision is 1.4 m/s and the the mass of the target ball is 1.832 kg.

But according to your question
On a planet with gravity 1/10 of the earth is
Weight = force = mg /10.
On the Moon, gravity pulls less on objects so they weigh less. For example, a rock that weighs 1 pound weighs less on Earth than it does on the Moon. Weight is the result of the law of universal gravitation. Any two objects are attracted to each other by their masses with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
The mass remains the same and the weight decreases on the moon. When flying to the moon the gravitational acceleration is less than the gravitational acceleration. That's about one-sixth of the acceleration due to gravity. If gravity is halved, atmospheric pressure is halved. This equates to climbing above 5,000 meters.

If the distance between two objects is decreased to one fourth of the original distance, how will this decrease change the force of attraction between the objects?
If the distance between two objects is decreased to one fourth of the original distance, then the new force of attraction between the objects will be 16 times the initial force.
How to determine the new force of attractionFrom Newton's law of universal gravity, the force of attraction between two objects is given as:
F = GM₁M₂ / r²
Where
F is the force of attraction K is the electrical constant M₁ and M₂ are the masses of the objects r is the distance apartObtaining a relationship between the force of attraction and the distance, we have:
F = GM₁M₂ / r²
Cross multiply
Fr² = GM₁M₂
GM₁M₂ = constant
F₁r₁² = F₂r₂²
With the above formula, we can obtain the new force of attraction as follow:
Initial distance apart (r₁) = rInitial force of attraction (F₁) = FNew distance apart (r₂) = 1/4r = 0.25rNew force of attraction (F₂) =?F₁r₁² = F₂r₂²
F × r² = F₂ × (0.25r)²
Fr² = F₂ × 0.0625r²
Divide both side by 0.0625r²
F₂ = Fr² / 0.0625r²
F₂ = F / 0.0625

s = 0 + ( 1 / 2 * 9.8 * t² )
s = 4.9 t²
If the time value is accurate to one-tenth of a second, then two time values multiplied will be accurate to one-hundredth of a second and so will the height in turn which will be measured in meters.
Therefore, if the time is measured accurately to a tenth of a second, the height calculated will be precise to one hundredth of a meter.

The effiency of a single movable pulley is not 100% .Give 2 reason
The efficiency of a single movable pulley is not 100 % because the applied load is half of the load to be lifted.
MA = Fo / Fi
MA = Mechanical advantage
Fo = Output force
Fi = Input force
In a single movable pulley,
Fi = 0.5 Fo
MA = Fo / 0.5 Fo
MA = 2
Efficiency = MA * 100
Efficiency = 2 * 100
Efficiency = 200 %
A movable pulley does no have a fixed axis of rotation. In a movable pulley the forces are multiplied at the other end. So the effort required to pull the load is easier than a fixed pulley.
Therefore, the efficiency of a single movable pulley is not 100%

If an object travels 1500 m in 50 s, then what is its average
velocity?
a 30 m/s
b 50 m/s
c 1450 m/s
d 1500 m/s
Answer:
a 30 m/s
Explanation:
average velocity = total displacement/ total time taken
therefore a. velocity = 1500/50 which gives 30 m/s.
when an electron circles in a uniform motion, what would happen if we increased the magnitude of the magnetic field?
If we increased the magnitude of the magnetic field The radius would decrease.
What is a magnitude?Magnitude in physics is basically "distance or quantity," so it represents the relative or absolute size, direction, or speed of an item. It is employed to describe something's size or scope. Magnitude in economics generally refers to a size or quantity.
Does magnitude mean force?The total amount of forces exerted on an item is referred to as the magnitude of force in physics. The intensity of the force increases when all of the forces are pulling in the same direction. As forces are exerted on an item from different angles, the agency's strength reduces.

What characteristic of a wave did we learn is related to the intensity or loudness of a sound?.
The amplitude of the wave is related to the intensity or loudness of the sound.
What is amplitude?
A periodic variable's amplitude measures its change over a single period (such as time or spatial period). A non-periodic signal's magnitude in relation to a standard value is its amplitude. There are several definitions of magnitude, all of which depend on how much the extreme values of the variable differ from one another. The phase of the a periodic function sometimes is referred to as the amplitude in older texts. The maximum displacement of a wave propagating medium particle from its mean position to its extreme position is the amplitude.
