C. James Clerk Maxwell
I believe he made a theory that light was electromagnetic radiation
Answer:
A) 1.2
B) 1.1
Explanation:
A)
F = force required to start the box moving = 36.0 N
m = mass of the box = 3 kg
= weight of the box = mg = 3 x 9.8 = 29.4 N
= normal force acting on the box by the floor
normal force acting on the box by the floor is given as
= = 29.4
= Static frictional force = F = 36.0 N
= Coefficient of static friction
Static frictional force is given as
=
36.0 = (29.4)
= 1.2
B)
a = acceleration of the box = 0.54 m/s²
F = force applied = 36.0 N
= kinetic frictional force
= Coefficient of kinetic friction
force equation for the motion of the box is given as
F - = ma
36.0 - = (3) (0.54)
= 34.38 N
Coefficient of kinetic friction is given as
= 1.1
Answer:
The magnitude of the acceleration of the tip of the minute hand of the clock .
Explanation:
Given that,
Length of minute hand = 0.55 m
Length of hour hand = 0.26 m
The time taken by the minute hand to complete one revelation is
We need to calculate the angular frequency
Using formula of angular frequency
Put the value into the formula
We need to calculate the magnitude of the acceleration of the tip of the minute hand of the clock
Using formula of acceleration
Put the value into the formula
Hence, The magnitude of the acceleration of the tip of the minute hand of the clock .

Answer:
Physics is a brand of science that deals with nature, matter, and energy. Physics is used in the everyday world because we have simple objects such as levers that use physics. we also have Newton's law of transportation that manipulate everyday objects making them move, so without physics many objects wouldn't move.
