A force is required for any change in an object's motion to occur.
True
False
Answer:
True
Explanation:
an object in motion stays in motion unless acted upon by another force
Answer/Explanation:
True. A force is what causes a movement in the first place. In order for an object to change motion a different force must be applied such as its opposing force.
Natural force: Thrust
Opposing force is drag.
Other forces are gravity and lift.
The opposing force will reverse the motions direction, the other forces will just change the direction without reversing.
Explain how land breezes occur, in as much detail as you can
Answer:
The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.

Hello!!
For calculate the resistance of the toaster, we have to applicate formula:
[tex]\boxed{R= V^{2}/P}[/tex]
[tex]\textbf{Being:}[/tex]
[tex]\sqrt{}[/tex] [tex]P = Potency \ power = 1500 \ W[/tex]
[tex]\sqrt{}[/tex] [tex]V = Voltage = 120 \ V[/tex]
[tex]\sqrt{}[/tex] [tex]R = Resistance = \ ?[/tex]
[tex]\text{Then let's \textbf{replace it according} we information:}[/tex]
[tex]R = (120 \ V)^{2} / 1500 \ W[/tex]
[tex]R = 9.6 \ \varOmega[/tex]

50 cm3 of a gas are in
20°C calculate the
new volume at 96°C
Given :
Volume of gas in 20°C is 50 cm³.
To Find :
The new volume at 96°C.
Solution :
Let, us assume that the pressure is constant throughout the process.
We know, when pressure is constant volume is directly proportional to the temperature.
So, [tex]\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}[/tex]
Putting all values in above equation, we get :
[tex]\dfrac{50}{V_2}=\dfrac{273+20}{273 + 96}\\\\V_2 = 50\times \dfrac{369}{293}\ cm^3\\\\V_2 = 62.97\ cm^3[/tex]
Hence, this is the required solution.

What is electric circuit?Electric circuit is a way for electric current to be transmitted. A lamp, an electric motor, a computer, and the connecting wires or transmission lines are examples of current-using equipment. An electric circuit also contains a device that provides energy to the charged particles that make up the current, such as a battery or a generator. Kirchhoff's principles and Ohm's law are two fundamental laws that mathematically define how electric circuits operate.
According to fig, only 1 and 3 rings have one way of passage of electric current. So, when 1 or 3 ring will be removed from the circuit, the circuit becomes open and no current passing through the circuit and the bulb stops glowing.

Find the mass of a 52.2N bucket.
Answer:
m = 5.22 kg
Explanation:
The force acting on the bucket is 52.2 N.
We need to find the mass of the bucket.
The force acting on the bucket is given by :
F = mg
g is acceleration due to gravity
m is mass
[tex]m=\dfrac{F}{g}\\\\m=\dfrac{52.2}{10}\\\\=5.22\ kg[/tex]
So, the mass of the bucket is 5.22 kg.

4. Joe and his brother Bo have a combined mass of 200.0 kg and are zooming along in
a 100.0 kg amusement park bumper car at 10.0 m/s. They bump into Melinda's car,
which is sitting still. Melinda has a mass of 25.0 kg. After the collision, the twins
continue ahead with a speed of 4.12 m/s. How fast is Melinda's car bumped across
the floor?
Answer:
Joe & Bo's car: 200.0 kg + 100.0 kg = 300.0 kg; Melinda's car: 25.0 kg + 100.0 kg = 125.0 kg
so the answer is 125.0kg

Which of these takes about 365 days to complete? Earth rotating once on its axis Earth rotating once on its axis Earth revolving once around the Sun Earth revolving once around the Sun the moon revolving once around Earth the moon revolving once around Earth the sun revolving once around Eart
Answer:
Earth revolving once around the Sun
Explanation:
The Earth is one of the planets that make up the Solar system. The earth undergoes two phenomena called "ROTATION" and "REVOLUTION". Rotation refers to the moving around of an object along its own axis while revolution refers to the moving of an object around another object.
The Earth rotates (along its axis) to produce the day and night (24 hours). However, the revolution of the Earth around the largest planetary body, which is the SUN, takes approximately 365 days to complete. Hence, the Earth's revolution around the sun produces the year (365 days).

A 55-kg skater moving at 2.5 m/s overtakes a 45-kg skater moving at 1.0 m/s in the same direction and collides with her. The two skaters stick together. What is their final speed?
Answer:
1.825m/s
Explanation:
Using the law of conservation of momentum which says that momentum before collision is equal to sum of momentum after collision.
m1u1+m2u2 = (m1+m2)v
m1 and m2 are the masses
u1 and u2 are the initial velocities
v is final velocity of the two bodies after collision
Substitute the given parameters into the formula
55(2.5)+45(1) = (55+45)v
137.5+45 = 100v
182.5 = 100v
v = 182.5/100
v = 1.825m/s
Hence their final speed is 1.825m/s

a) 1

5. A boat increases its speed from 5.0 m/s to 7.5 m/s over a
distance of 50.0 m. What is the boat's acceleration?
Answer:
(v2² - v1²)/(2x) = (7.5² - 5.0²)/(2*50) = 0.3125 m/s²
The acceleration of the boat is 0.16 m/s².
We have a boat.
We have determine the boat's acceleration.
What is Acceleration ?The rate of change of velocity with time is called Acceleration.
a = dx/dt
According to the question -
Initial velocity (u) = 5m/s
Final velocity (v) = 7.5m/s
Distance (d) = 50 m.
Now -
v²- u² = 2aS
(v + u)(v - u) = 2aS
12.5 x 2.5 = 200 a
a = 0.16 m/s².
Therefore, the acceleration of the boat is 0.16 m/s².

He's 76.2 W lightbulb uses 66.2 J of electrical energy every second. However, only 4.9 J of electrical energy is converted into light energy of each check and what is the efficiency of the lightbulb? Give your answer as a percentage to at least three decimal places
Answer:
7.402%
Explanation:
Given that the total electrical energy used by the bulb in every second is 66.2 J.
The useful energy converted to light energy is 4.9 J.
As efficiancy (in %) = (Useful energy)/(Total energy) x 100
So, the efficiency of the bulb = (4.9/66.2)x100=7.402%
Hence, the efficiency of the bulb is 7.402%.
