To solve this problem we will apply Newton's second law, which indicates that the force is equivalent to the product between mass and acceleration, so
Here,
F= Force
m = Mass
a = Acceleration
Rearranging to find the mass we have,
The value of the acceleration is
Replacing to find the mass,
Now in ponds this value is
Therefore the mass of the spacecraft is 52.8lb
Answer: r^-1
Explanation:
V = (k × Q) / r, where V is electric potential, k is constant and r is distance from charge.
Since Q will not change, it can be considered a constant too.
So, we can write V ∝ 1/r
which is same as V ∝ r^-1
The answer is 4.7 m for the spàthan. this is a very question! I hope this helps my friend! :-)
Answer:
Explanation:
The volume flow rate of a fluid in a pipe is given by:
where
A is the cross-sectional area of the pipe
v is the speed of the fluid
In this problem, at the initial point we have
v = 0.84 m/s is the speed of the water
r = 0.21 m is the radius of the pipe, so the cross-sectional area is
So, the volume flow rate is
