The force needed to accelerate an elevator upward at a rate of is 2000 N or 2 kN.
<u>Explanation:
</u>
As per Newton's second law of motion, an object's acceleration is directly proportional to the external unbalanced force acting on it and inversely proportional to the mass of the object.
As the object given here is an elevator with mass 1000 kg and the acceleration is given as , the force needed to accelerate it can be obtained by taking the product of mass and acceleration.
So 2000 N or 2 kN amount of force is needed to accelerate the elevator upward at a rate of .
Answer:
706.5 g
Explanation:
density of fluid, d = 1.35 g/c.c
According to the principle of flotation
Weight of the frog = Buoyant force acting on the frog
V x density of frog x g = V x density of fluid x g
So, the density of frog = density of pod
Mass of frog = volume of frog x density of frog
M = 4/3 πr³ x d
M = 4/3 x 3.14 x 5 x 5 x 5 x 1.35
M = 706.5 g
Thu,s the mass of frog is 706.5 g .
The most suitable answer would be [D] Cool because that is the most common weather to pursue physical weathering.
