Answer:
<h2>4.3 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
430 g = 0.43 kg
We have
force = 0.43 × 10
We have the final answer as
<h3>4.3 N</h3>
Hope this helps you
Answer:
The point on the rim
Explanation:
All the points on the disk travels at the same angular speed , since they cover the same angular displacement in the same time. Instead, the tangential speed of a point on the disk is given by
where
is the angular speed
r is the distance of the point from the centre of the disk
As we can see, the tangential speed is directly proportional to the distance from the centre: so the point on the rim, having a larger r than the point halway between the rim and the axis, will have a larger tangential speed, and therefore will travel a greater distance in a given time.
Earth is surrounded by a blanket of air called the atmosphere.
All living organisms depend on this atmosphere to survive as the atmosphere provide the necessary air that we breath and also protects us from the harmful radiations of the sun.
The atmosphere is mainly composed of four layers which are:
1- Troposphere which has the air that we breath
2- Stratosphere which has the ozone layer
3- Mesosphere
4- Ionosphere
