Which literal equations are equivalent to w = Fd? Choose all answers that are correct.A. d = fw
B. d = wf
C. f = wd
D. f = dw

Answers

None of the given choices would be equivalent to the equation w = F x d. If I am given the freedom to give equivalent expressions for the given equation those would be,
w / d = F or w / F = d
If we multiply the denominator of the left hand side of the equation to the term in the right, we get the original equation.

Surprisingly, NONE of the choices is equivalent to. W=fd .

two plane mirrors are at right angles to each other. a man stands between them and combs his hair with his right hand. in how many of the images will he be seen using his right hand? none 1 2 3

Answers

Explanation:

In the first two images the comb would be in the left hand of the man. The image which appears in between those two images has the comb in its right hand. Therefore, the images in which he will be seen using his right hand is one.

The least common shape for a galaxy is ______. irregular elliptical cluster spiral spherical

Answers

Answer: cluster

Explanation:

There are four main shapes of galaxies: spiral, galaxies are divided into four main groups: spiral, lenticular, elliptical, and irregular, elliptical, and irregular.

The least common shape is cluster

Spiral galaxies- These are the most common. These have arms extending from a bright bulge in spiral shape.

Elliptical galaxy have ellipsoidal shape.

Lenticular galaxies - Intermediate between elliptical and spiral galaxies.

Irregular shape- No well defined shape

Spherical - Nearly spherical galaxies. These are least

cluster- group of galaxies having irregular shape is the least common shape.

Question: The least common shape for a galaxy _____.

Answer:Cluster

What is the gravitational force acting on a 70.0 kg object standing on the earth's surface ?

Answers

g( gravitational acceleration)=-9.81 m/s^2
m(mass) = 70.0 kg

According to Newton's second law of motion:

"F=ma"

Force is equal mass per acceleration therefore

W=mg
This is because weigth is the force of gravity acting in a body and "a" is replaced by "g" because "g"
is gravitational acceleration

Therefore:

W= mg
W= (70.0 kg) (-9.81m/s^2)
W= -686.7 N

* The "N" means newton which is (kg* m/s^2)

Final answer:

The gravitational force acting on a 70.0 kg object on Earth is calculated using the formula w=mg and is equal to 686 N.

Explanation:

The gravitational force acting on a 70.0 kg object standing on the earth's surface can be calculated using the formula for weight (which is essentially the gravitational force on the object): w = mg, where m is the mass of the object and g is the acceleration due to gravity. On Earth, g is approximately 9.8 m/s².

Therefore, the gravitational force (weight) acting on this object can be calculated as follows: w = mg = (70.0 kg)(9.8 m/s²) = 686 N. Thus, the gravitational force on this 70.0 kg object standing on the earth's surface is 686 Newtons. It's important to understand that this force will vary if the object is moved to a location where g is different, like on the moon.

Answers

Answer:A- Gamma rays

Explanation:

Gamma rays are most dangerous among all the given rays because it has the highest frequency i.e. high penetrating tendency. They can also pass through bones and teeth and this is the reason for their potential hazard.

They can destroy the living cell, initiate gene mutation and can cause cancer.

But they can also be used for destroying cancer cells.
