Answer:
The distance the car traveled during the given time is 94.44 m.
Explanation:
Given;
time of motion t = 8 seconds
initial velocity, u = 15 km/hr = 4.167 m/s
final velocity, v = 70 km/hr = 19.444 m/s
The distance traveled by the car during this time is given by;
Therefore, the distance the car traveled during the given time is 94.44 m.
Answer:
Kinetic energy is the amount of energy a object has while it's in motion, and thermal energy is heat energy. In this case when the heat rises in substances for example a solid it will transform into a liquid causing the molecules to move faster which is a increase of kinetic energy.
Explanation:
Answer:
True
Explanation:
Objects have the same velocity only if they are moving at the same speed and in the same direction.
Answer:Let m = mass of asteroid y.Because asteroid y has three times the mass of asteroid z, the mass of asteroid z is m/3.Given:F = 6.2x10⁸ Nd = 2100 km = 2.1x10⁶ mNote thatG = 6.67408x10⁻¹¹ m³/(kg-s²)The gravitational force between the asteroids isF = (G*m*(m/3))/d² = (Gm²)/(3d²)orm² = (3Fd²)/G = [(3*(6.2x10⁸ N)*(2.1x10⁶ m)²]/(6.67408x10⁻¹¹ m³/(kg-s²)) = 1.229x10³² kg²m = 1.1086x10¹⁶ kg = 1.1x10¹⁶ kg (approx)Answer: 1.1x10¹⁶ kg
