Answer:
D.) A 15 kg mass moving at 2.0 m/s
Explanation:
The inertia of an object is most directly related to its mass and not the magnitude of the velocity.
So, the higher the mass of an object, the more its inertia.
According to Newton's first law of motion "an object will remain in its state of rest or of constant motion unless it is acted upon by an external force".
- Inertia is the tendency of a body to remain in a state of rest either by virtue of its static position of constant motion.
- The larger the mass, the more this tendency.
- An object with a large mass will take more force to bring it from rest or change its motion.
Answer:
Explanation:
Using
4.01 × 10^3 * 4.186 = 1.72×10^4j
In KJ 17.2kj
The lower the frequency the lower the pitch sound.
Answer:
3 x 10^5 J
Explanation:
mass of substance, m = 1 g = 0.001 kg
Velocity of light, c = 3 x 10^8 m/s
According to the Einstein mass energy equivalence, the energy associated with the mass is given by
E = m c^2
E = 0.001 x 3 x 10^8
E = 3 x 10^5 J
