Answer:
a = 1.25m/s^2
Explanation:
Force = mass x acceleration
Given mass M = 48kg and
Force F = 60N
60 = 48 x a
Divide both sides by 48
60/48 = 48 x a/48
1.25 = a
a = 1.25m/s^2
false the answer is Exosphere :D
hope this helps have an amazing day and be safe
Answer:
Convection is heat transfer through the movement of liquids and gases.
Answer:
a. Photogates placed at the beginning, end, and at various locations along the track that the car travels on.
b. A meterstick to measure the distance of the track that the car travels on.
Explanation:
Physics can be defined as the field or branch of science that typically deals with nature and properties of matter, motion and energy with respect to space, force and time.
In this scenario, a student is provided with a battery-powered toy car that the manufacturer claims will always operate at a constant speed. The student must design an experiment in order to test the validity of the claim.
Therefore, to test the validity of the claim, the student should use the following measuring tools;
a. Photogates placed at the beginning, end, and at various locations along the track that the car travels on. This device is typically used to measure time with respect to the rate of change of the interruption or block of an infra-red beam.
b. A meterstick to measure the distance of the track that the car travels on.
Hence, with these two devices the student can effectively measure or determine the validity of the claim.
