Explanation:
Initially, the object is at rest, u = 0
Acceleration of the object,
(a) Distance travel in 2 second can be calculated using second equation of motion as :
(b) Distance travel in 4 second can be calculated using second equation of motion as :
(c) Initial velocity of the object, u = 4 m/s
(d)
Hence, this is the required solution.
Answer:
V = I × R and the power law equation (formula): P = I × V. P = power
Answer:
b. 0 J
Explanation:
Work is the cross product of force and displacement. Since the bucket has 0 displacement, the net work is 0 J.
Answer:
p>Whether an object will float or sink is dependent on its density, and on the density of the liquid it is placed in. In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level.
the car travels 34 mi in one hour.
then, in 6 hours car travels
34 x 6 mi
= 204 mi
