Answer:
D
Explanation:
cause the slope works with going up or down
Answer:
Explanation: The time taken by the object to reach the ground depends up on the vertical velocity of the object.
The object horizontal velocity component only moves the object in forward direction and does not have any effect vertically
as the object is launched horizontally its initial vertical velocity is zero
the object experiences downward fall due to gravitational acceleration only since there is no air resistance
therefore a=g
the distance covered =s=h
now the kinematic equation could be used
Answer: [tex]12.415 rad.s^{-1}[/tex]
Explanation: Angular velocity is the rate of change in angular displacement.
We know that:
Angular velocity, ....................(1)
where:
- = angular displacement in radians
<u>Given that:</u>
Putting the respective values in eq. (1)
Answer:
The read will be 20.9[C]
Explanation:
This is a problem related to linear interpolation, Linear interpolation consists of tracing a line through two known points y = r (x) and calculating the intermediate values according to this line.
The equation of a known line two points (x1, y1)and (x2, y2) = (2,0) (100,95) is:
If we clear y from the equation we have:
[tex]y=\frac{(x-y_{1})}{(x_{2}-x_{1} )}*(y_{2} -y_{1} )+y_{1} \\replacing
