Which of the following are not conditions for producing work?
2 answers:
Answer:
A and C
Explanation:
We know that
Work done,W=Fd
Where F=Applied force
d=Displacement of object
Momentum, p= mv
It is not necessary that momentum must be greater than force .If momentum is less than force then the work can be produced because work depend upon displacement and applied force.
If the value of theta is not equal to zero the work can be produced if theta is equal to 30 ,45 or 60 degree.
Therefore, it is not necessary that atleast part of the applies force must act along the same line object moves.
If force is greater than weight then, the work can be produced .
If force is less than the weight then, the work cannot be produced .
Hence, the force must be very large.

The constant velocity that the spacecraft must travel is : 3.49 * 10⁸ m/s
<u>Given data :</u>
Distance of star from earth = 4.3 light years
Observers time = 3.7 years
<h3>Determine the constant velocity the spacecraft must travel </h3>Observers time = 3.7 * 365 * 24 * 60 * 60
Distance of star from earth = 4.3 * 9.46 * 10¹⁵
The velocity the spacecraft must travel will be calculated using the equation
V = distance / time
= ( 4.3 * 9.46 * 10¹⁵ ) / ( 3.7 * 365 * 24 * 60 * 60 )
= 3.49 * 10⁸ m/s
Hence we can conclude that The constant velocity that the spacecraft must travel is : 3.49 * 10⁸ m/s
