Answer:
The correct answer is B. 0.64 m/s²
Explanation:
According to the Newton's Second law of motion acceleration of an object by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force.
Mathematically,
F ∝ a
F = ma
Given data:
Force = F = 35 N
Mass = m = 55 kg
acceleration = a = ?
F = ma
a = F/m
a = 35/55
a = 0.64 m/s²
Answer
a) Draw an upward force from the bottom to indicate upthrust
b) Upthrust is an upward force acting on an object floating on a liquid... hence there is an upward force acting on the iceberg which causes it to float.
c) Unfortunately I don't know the answer.
A. Insulator paper is a good insulator of heat
Answer:
Gravity
Explanation:
Gravity applies a constant downward force on the cars. The coaster tracks serve to channel this force — they control the way the coaster cars fall. If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates
The object that had the most 1000 ton weight has the most momentum
