Average speed = distance travelled / time used
Answer:
m=30.581kg
<em>If you use 10m/s/s for your value of g then the answer is 30kg)</em>
Explanation:
Assuming this is happening on earth, acceleration due to gravity (g) is 9.81m/s/s.
Force of gravity is the acceleration due to gravity multiplied by its mass:
F=mg
300=(9.81)m
m=30.581kg
<em>If you use 10m/s/s for your value of g then the answer is 30kg)</em>
In one of the greatest coincidences to arise on Brainly in quite some time, Choice-C is the correct choice for BOTH #15 and #16 .
Choice-C is the only situation in which the source is a different distance from each ear.
Answer:
2.52N
Explanation:
according to law of moments ,
F1L1=F2L2 ,where the forces are in equilibrium .
0.85(44.5)= 15F2
that is , taking their distances from 50cm point
37 .825=15F2
37.825÷15= F2
2.52N = F2
