What is the mass of an object if a force of 34 N produces an acceleration of 4 m/s2?

Answers

F = ma
Force = mass * acceleration

Switch the question to be:
Mass = force/acceleration

34 Newtons/4 m/s = m
M = 8.5 kg

Answer should be: The mass is 8.5 kg

The mass is 8.5 kg

Answer: magnitude = 5 and angle = 160°

Explanation:

A vector has magnitude 5 and angle -20°

A vector can be written in terms of its components as :

$\vec{A}=A_x\hat{i}+A_y\hat j \n \Rightarrow \vec A = A cos\theta \hat i+A sin\theta \hat j$

using trigonometry identity:

sin θ = -sin ( 180 + θ )

cos θ = - cos (180 + θ)

Thus, we can write the same vector as:

$\vec A = -A cos(180+\theta) \hat i+(-A) sin(180+\theta) \hat j$

Magnitude $|A|=√((-A)^2+(-A)^2) = A = 5$

Thus, the magnitude would be A = 5 and angle = 180+θ= 180-20 = 160°

A converging lens can produce both real and virtual images depending on the position of the object. Explain when converging lenses can produce virtual images and describe the image produced.A) A virtual image is produced if the object is on the focal point, the image is upright, enlarged and on the same side of the lens as the object.

B) A virtual image is produced if the object is on the focal point, the image is inverted, enlarged and on the opposite side of the lens from the object.

C) A virtual image is produced if the object is between the focal point and the lens, the image will be upright, enlarged and on the same side of the lens
as the object.

D) A virtual image is produced if the object is between the focal point and the
lens, the image will be upright, reduced and on the opposite side of the
lens from the object.

Answers

A virtual image is produced if the object is between the focal point and the lens.

What is a converging lens?

A converging lens is a lens that can produce both real and virtual images depending on the position of the object.

Answer: C

Explanation:

In a game of pool why will the balls eventually stop after a collision

Answers

Everything we see happening on Earth has friction along with it.
For a pool ball, it's the work the ball does bending all the little cloth
fibers out of the way as it rolls along the table, and also the work it
does pushing air out of the way. These things rob a little bit of each
ball's kinetic energy, so that it eventually stops rolling.

Note: Gravity is not the answer.
