Answer:
Normal force = 8.75 N
Explanation:
given,
frictional force between the steel spatula and the Teflon frying pan=0.350 N
coefficient of friction between material =0.04
normal force = ?
using formula,
Frictional force = coefficient of friction × normal force
Normal force = 8.75 N
Answer:
The acceleration greater at the beginning of this process
Explanation:
The car when starting to move is necessary an acceleration therefore at the beginning of the movement there is an acceleration. The engine power is at a constant value so that when the car reaches the maximum speed (constant speed) at that power there will be no acceleration.
That is to say, at constant speed = zero acceleration
And of course this final null acceleration will be less than the initial acceleration so that the car starts to move

The length of the new runway In terms of (L) is 4L.
<em />
<em>Your question is incomplete, it seems your question is missing the following information below;</em>
"In terms of (L) , what must be the length of the new runway?"
The given parameters;
- length of the runway, = L
- let the take off speed = V₁
For the newly designed planes;
the take off speed is double of the original = 2V₁
the acceleration for both take is constant = a
The take off speed for the given constant acceleration is given as;
The length of the new runway In terms of (L) is calculated as follows;
Thus, the length of the new runway In terms of (L) is 4L.

<span>In this situation when using newton's third law, the floor is very rigid and thus when we fall the floor applies
the same amount of force on us with which we were falling on it. The rigidness of the concrete floor makes it difficult for it to absorb some of our force. On the other hand sand is not rigid on impact sine it changes its shape while it absorbs a
large amount of our falling force and a small fraction of this
force is applied on is. That is why we don't get hurt</span>
