The correct answer is c.
work is calculated by force * distance less force means less work there its self explanatory c
Answer:
<em>The hang time is 2.04 seconds</em>
Explanation:
<u>2-D Motion
</u>
It referred to as a situation where an object is launched in such a way it describes a curve, reaches a top height and then returns to ground level after traveling a certain distance x away from the launch point.
Let be the launching speed forming an angle with the horizontal reference. The hang time (time the object remains in the air) is given by
Since
Then
We'll use the given values
The hang time is 2.04 seconds
Answer:
see below
Explanation:
to find distance multiply speed by time
to compute speed the formula is distance divided by time
here is to learn the triangle
Search up distance, speed and time triangle
it is much easier to remember
hope this helps
please mark it brainliest
Answer:
Yes it is possible to charge balloon to several thousand of volts and the balloon will also store several Joules of energy.
Explanation:
By rubbing a balloon on one's hair or on different types of clothing, the balloon either gain or loss electron.
If the balloon gains electron it becomes negatively charged, it contains more electron and subsequently charged to several thousand volts.
Also, if the balloon losses electron, it becomes positively charged. In this case it contains more proton, which makes the balloon positively charged to several thousand volts.
However, amount of joules depends on volts produced in the balloon.
Volt = Joules/coulomb,
Joules = volts*coulomb
Because the charge of the particles (electron and proton) are small, amount of joules will always be small than volts.
So, it is possible to charge balloon to several thousand of volts and the balloon will store several Joules of energy
Answer:
147.27N
Explanation:
Power = workdone/time
Power = Force*distance/time
Given
Power = 90Watts
Distance = 1.1m
Time = 1.8secs
Force = ?
Substitute the given parameters into the formula:
Hence the magnitude of the force that you exert on the handle is 147.27N
