Answer:
Explanation:
Given data
Mass of elevator m=3.0×10³kg
Time t=23 seconds
Height d=210 m
Concept:
Power is defined as rate at which work is done by force is said to be the power due to force.
The power can be calculated as
First we need to find the force by applying newtons law of motion
So
Now we need to find the velocity V
So
Now to put values of Force and velocity to find the power.As the force have same direction of motion so angle is zero
The position of the first ball is
while the position of the second ball, thrown with initial velocity , is
The time it takes for the first ball to reach the halfway point satisfies
We want the second ball to reach the same height at the same time, so that
The heaviest of these gases would be SO2, or Sulfur Dioxide.
Answer:
The right solution is "".
Explanation:
Given that,
q = 0.50 nC
d = 900 mm
As we know,
⇒
By putting the values, we get
⇒
⇒
