Following your push the ball rolls down the lane at 4.2m/s. What is the net force on the ball as it rolls down the lane at the constant speed?
Answer:
Polarization.
Reason being that phenomena verifies the transverse nature of light
Answer:
3.7 m/s^2
Explanation:
The period of a pendulum is given by:

where L is the length of the pendulum and g is the free-fall acceleration on the planet.
In this problem, we know that the period of the pendulum on Earth is:

while the period of the same pendulum on Mars is

And since the length of the pendulum L does not change, we can write:

where
is the free-fall acceleration on Earth
is the free-fall acceleration on Mars
Re-arranging the equation and substituting numbers, we find:

Answer:
The power drawn by the toaster is closest to:
(A) 370 W
Explanation:
First we calculate the resistance of the nichrome wire (R).

Where radious (r), resistance coefficient (p), and Length (L)

After replace the value in the ohm law power formula to obtain the power consumed:

Answer:
M = 60x
M = 150x
M = 675x
M = 1455 x
Explanation:
In a microscope the total magnification is found by multiplying the magnification of the ocular (eye piece) and objective lens.
=Ocular magnification = 15x
=Objective magnification = 4x
Total magnification

M = 60x

M = 150x

M = 675x

M = 1455 x
