Answer:
a)
b)
Explanation:
Given:
- x-component of avg. velocity,
- x-component of avg. velocity,
- initial position of rhino,
- initial time,
- final time,
a)
As we know that average velocity is total displacement per unit time.
Position of x-coordinate of rhino:
Position of y-coordinate of rhino:
b)
<u>Now the distance from the origin:</u>
speed=frequency*wavelength, so frequency=speed/wavelength. frequency=80*0.2
Frequency = 16 Hz
Any source of heat can cause the liquid in the thermometer to rise. Heating the liquid would increase the liquid in the thermometer, as well as adding other liquids that might spark a thermal chemical reaction.
A current is just the development of electrons. Since there is no electric field from a (steady) current, this implies the wire is still electrically unbiased, ie uncharged. Accordingly the appropriate response is no charge. I trust the appropriate response will help you.
Answer:
Part a)
Part b)
Part c)
Explanation:
Velocity just before it strike the ground is given as
since there is no friction in horizontal direction so its speed in horizontal direction will remain same
Part a)
velocity in X direction
time taken by the skier to reach the ground is given as
now in the same time it will cover vertical distance
so magnitude of initial speed is given as
Part b)
Direction of velocity
Part c)
Now in order to find the height of the ramp we can find the vertical displacement
