Answer:
frictonal force due to the surface of irregularities
Answer:
60Nm
Explanation:
Given data
Applied force= 200N
length of spanner= 30cm to meter
= 30/100= 0.3m
We know that the formula for the moment is
P=Fl
that is
P= force * length
P= 200*0.3
P= 60Nm
Hence the moment is 60Nm
Newton's 1st law of motion states that <span>an object at rest stays at rest and an object in uniform motion along a straight line stays in motion unless acted upon by an unbalanced force.
This law talks about the tendency of an object to resist any change in its state of rest or uniform motion, this is called Inertia. Thus Newton's 1st law of motion is also called the Law of Inertia</span>
You didn't mention it, but the trumpeter herself has to be standing still.
<span>Person C, the one running towards the trumpeter, hears a pitch
that is higher than B-flat. (A)
Person B, the one running away from the trumpeter, hears a pitch
that is lower than B-flat.
Person D, the one standing still the whole time, hears the B-flat.</span>
