C. Volcanoes above subduction zones have lava that is not basaltic.
<h2>Answer :</h2><h2 />
Work is the amount of energy transferred. As per the formula
Work = Force x Distance [moved toward the direction of the force]
So as per the formula
<u>Solution : </u>
Force = 825 N
Distance = 35 m
Work = 825 (n) x 35 (m)
Work = 28875 Joules

Answer:
The correct answer is V√5
Explanation:
Let V be the velocity of the satellite orbiting at radius r.
Let V(5r) be the velocity of the satellite orbiting at radius 5r.
Recall:
Escape velocity is given by:
V = √(2gr)
Where V is the escape velocity
g is the acceleration due to gravity
r is the radius of the earth.
With the above equation, we can obtain the answer to the question as follow:
V = √(2gr)
V(5r) = √(2g5r)
Next, we'll obtained the ratio of V(5r) to V as shown below
V(5r) : V => V(5r)/V
V(5r)/V = √(2g5r) / √(2gr)
V(5r)/V = √5
Cross multiply
V(5r) = V√5
From the above illustration, we can see that when the satellite is moved to 3r, then the expression for the velocity will be V√5
speed of the striking object is given as
now this speed in SI units given as
So here we can use kinematic now to find the height from where it is dropped
so here we will have
now we have
now from above equation
now we know that average height of 1 story building is 3 meter
so approx total number of stories in the building will be
