Answer:
1.43 kg
Explanation:
We can solve the problem by using Newton's second law:
where
F is the net force on an object
m is its mass
a is its acceleration
For the squirrel in the problem, we have:
is the acceleration
F = 5 N is the net force acting on it
Solving for m, we find its mass:
Answer:
Option-A
Explanation:
In the given question, two cyclists of equal weight are riding the same mountain with cycles of the same weight but Joe reaches the top before Bob.
This scenario can be explained in terms of power and if we ignore the force of wind resistance and friction. Power refers to the work done per unit time, therefore, P= W/t. Since Joe rides up straight earlier than Bob shows that Joe has exerted more power than Bob that is the amount of work done by the Joe is greater than Bob.
Thus, Option-A is the correct answer.
Answer:
186 N
ExplanatioN
Weight is essentially just a measurement of the force of gravity, so you can use this equation.
F = mg
Force = Mass × Acceleration due to Gravity
F = 19kg × 9.8m/s^2. (Acceleration due to Gravity on Earth.)
F = 186.02N
Graduated cylinder is your answer
