Remain the same
Explanation:
If the force exerted by the intern is doubled and the distance is halved, the work done by the intern remains the same.
Work done is the force applied to move a body through a distance.
Work done = F x d
where F is the applied force
d is the distance moved
Now;
if:
f = 2f
d = d
Input the parameter:
Work done = fxd = 2f x d = fd
The work done will still remain the same

Answer:
Explanation:
The speed of sound in the air increases 0.6 m / s for every 1 ° C increase in temperature. An approximate speed can be calculated using the following empirical formula:
Where:
A more exact equation, usually referred to as adiabatic velocity of sound, is given by the following formula:
Where:
Hence:
Now, the Mach number at which an aircraft is flying can be calculated by:
Where:
Therefore:
Answer:
The magnitude of each force is 1309 N and 105 N
Explanation:
The reaction at each lifter due weight and overturning effect (R₁, R₂) is given as:
g = 9.8 m/s²
Resolving the reactions to the vertical direction, we get:
The magnitude of each force is 1309 N and 105 N
