The arrows always start at the magnet's north pole and point towards its south pole. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart
Answer:
350J
Explanation:
Given parameters:
Weight of bag = 20N
Distance moved horizontally = 35m
Force applied = 10N
Unknown:
Work done on the bag = ?
Solution:
Work done is the force applied to move a body through given distance.
Work done = Force applied x distance
So;
Work done = 10 x 35 = 350J
I think it’s B I could be wrong but I tried lol
In fact, the force Rahul exerts on Earth corresponds to the force of gravity. But Rahul's weight is, in fact, the force of gravity exerted by the Earth on Rahul, and these two forces correspond to the action-reaction pair of Newton's third law, which states that the two forces are equal.
An example of biological weathering is the widening of gaps
in rocks caused by tree roots since pressure or stress is exerted on the
rocks due to the growing plant roots. The pressure is exerted by a biological
process (i.e., growing roots), even though the process is physical.
Plants and animals and its action speeds up mechanical and or
chemical weathering, which in turn causes biological weathering.
<span>With the help of the chemicals
that are produced by the tiniest bacteria, algae and liches, the rocks which they
live in are also broken down by them in order to get the nutrients they need.</span>
