The movements of the tectonic plates
Answer:
P = 0.25 W
Explanation:
Given that,
The emf of the battry, E = 2 V
The resistance of a bulb, R = 16 ohms
We need to find the power delivered to the bulb. We know that, the formula for the power delivered is given by :

So, 0.25 W power is delivered to the bulb.
Answer
given,
before collision
mass of car A = m_a = 1300 kg
velocity of car A = v_a = 35 mph
mass of car B = m_b= 1000 kg
velocity of car B = v_b = 25 mph
after collision
V_a = 30 mph
V_b = 31.5 mph
Initial momentum



final momentum



here initial momentum is equal to the final momentum of the car.
hence, momentum is conserved in the collision.
Answer:
So I never really knew you
God, I really tried to
Blindsided, addicted
Felt we could really do this
But really I was foolish
Hindsight, it's obvious
Explanation:
Answer:
Change in potential energy is 700.7 J.
Explanation:
Given:
Mass of the object is,
kg
Height to which the object is raised above his head,
m
Acceleration due to gravity is,
m/s²
We know that for a mass
raised to a height
, the change in potential energy is given as:
, where, 
Now, plug in the given values and solve.

Therefore, the change in the potential energy is 700.7 J.
