Answer:
The objects exert the same force on each other.
Explanation:
Let us suppose that the mass of object 1 is greater than that of object 2. Both objects are at rest until an explosion occurs. The first object exert an equal and opposite force on another object as per Newton's third law of motion. In this case, Newton's third law will be applicable. As a result, he objects exert the same force on each other. Hence, the correct option is (a).
Answer:
C: Light travels from the Sun to the grass and is then reflected to your eyes.
Explanation:
Our eyes don't produce light but detect light (so answer A is not correct)
The grass doesn't produce light unless it is burning (discard answer B)
Answer C is the correct one.
The light we detect from the grass is not light bounced off the sky, it comes directly from the grass to your eyes (you are not looking at the sky when you see the grass) Discard answer D
Answer:
9375 N
Explanation:
From the question,
Centripetal force (F) = mv²/r.................. Equation 1
Where m = mass of the car, v = velocity of the car, r = radius of the curve.
Given: m = 900 kg, r = 600 m, v = 25 m/s
Substitute these values into equation 1
F = (900×25²)/600
F = 9375 N.
Hence the centripetal force on the car is 9375 N
