Answer:
The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension, T. When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.
The rubber protects him from being electrocuted by the flow of current going through the plug.
Hope this helped!!
Answer:
Because the surface area of her skis are greater than the surface are of her shoes
Explanation:
the reason for this is that the weight per in is too heavy crushing the snow blower but with the skies the weight is distributed to the point were the snow can support her weight
Answer:
Explanation:
Given:
- mass of bullet,
- initial velocity of bullet,
- displacement of the bullet in the target,
Here as given in the question the bullet penetrates the target by the given displacement of the bullet into it. During this process it faces deceleration and hence it comes to rest.
- so, final velocity of the bullet,
Now using the equation of motion:
where:
acceleration of the bullet
<u>Now the force of resistance offered by the target in stopping it:</u>
