Answer:
Since the weight of the ant is not given, we cannot determined the work done.
Explanation:
Given parameters:
Distance covered = 150m
Unknown:
Work done by mouse = ?
Solution:
To solve this problem, we need to understand that work done is the force applied to move a body through a certain distance.
In this case, work done;
Work done = force x distance
Work done = Weight x distance
Since the weight of the ant is not given, we cannot determined the work done.
The model is based on hypothesis to get an initial idea for analyzing a complex problem. Hence, the validity of a model is limited and may not be valid universally. On the other hand, theories and laws are confirmed hypothesis which are universally valid. These are formulated after repeated testings. theories are more explanatory.
Answer:
B AND D
HOPE ITS HELF FUL .........
As per Newton's II law we know that
here we know that
so here we will have
so here if we need to increase the acceleration we need to increase the applied force while on increasing the mass or on increasing the friction force the acceleration will decrease.
So here correct answer will be
<em>A) force on the object.</em>
Answer:
The graph appears to be in error.
The actual figure appears to be a rhombus with sides of 5 and 15 with a height of 5
The work done (F * S) is the area of the rhombus
1/2 * (5 +15) * 5 = 50 J
