Quick turn can lead to instability in the PWC. This may lead to the fall-off the passengers and operator. Therefore, everyone on a PWC should wear a personal floatation device and any passenger should never seat in front of the operator.
Answer:
Explanation:
The expression for the electric force between two charges
where K is the Coulomb's constant (k=9*10^{9}Nm^2/C^2), and we have that
q1=q
q2=3q
r=3.39m
F=2.4*10^{-6}N
By replacing in the formula we have
and by taking apart q we have
hope this helps!!
Answer:
W = 98 J
Explanation:
Given hat,
Force, F = 5 N
It is lifted 2 m off the ground.
We need to find the amount of work done. We know that, the work done by an object is given by the product of force and displacement. So,
W = Fd
or
W = mgd
Put all the values,
W = 5 × 9.8 × 2
W = 98 J
So, the work done is equal to 98 J.
Answer:
The boat's velocity relative to Earth is 3.91 m/s.
Explanation:
Given;
speed of ferry due north, = 2.5 m/s
speed of the river to the east, = 3.0 m/s
The boat's velocity relative to Earth is given by;
Therefore, the boat's velocity relative to Earth is 3.91 m/s.
Answer:
The electrostatic potential within the conductor will be negative and constant throughout the conductor.
Explanation:
Whenever a conductor is charged the total charge is spread throughout the entire surface uniformly. Inside the conductor the net electric field is always zero. Also we know if e the electric field and V is the potential, then
Now as in this case electric field within the conductor is zero, so potential (V) has to be constant.
