The weight of an object _____.

2 answers:

8 0

The weight of an object is the force with which it is attracted to earth. The gravity of an object or body of an object is high on earth than at the atmosphere. It has an average of gravitational constant equal to 9.8066 or 9.8 meters per second. In truth, the acceleration of the object depend upon its location, the latitude and altitude, on earth.

Answer : The correct option is d.

Explanation :

We know that the mass is the measure of the inertia of an object. it is equal to the amount of matter contained inside a body. It always remains the same.

The weight is equal to the force with which a body is attracted to earth.

Mathematically, weight of a body is given by :

W = m g

Where,

m is the mass of an object

g is the acceleration due to gravity.

The weight of an object varies with respect to location. Its SI unit is newton.

Hence, the correct option is (d) ''is the force with which it is attracted to earth''

Which theory suggests that the moon and the earth formed at the same time from dust and the solar nebula that formed the sun?

ad-work [718]

Answer: The correct answer is option(B.).

Explanation:

The co-formation theory explain that both moon and the earth are formed at same time from the primitive solar nebula (cloud made up of dust and gases) at the same and same place.

Where as capture theory suggests that the moon is an asteroid which was formed or created somewhere else in a solar system. And when the moon approached the earth planet it got captured by the earth's gravitational field.

Impact theory explains the formation of moon by the catastrophic collision between the earth and any planet half the size of earth's size.

Synchronous theory sheds the light on the rotation time, revolution time and sides of moon located from the surface of the earth.

Hence, the correct answer is option(B).

PHYSICS 50 POINTS PLEASE HELP

tangare [24]

Answer:

One way to look at Newton’s three laws of motion is this:

The third law states what forces are. That is, all forces are interactions between two different objects. If one object is interacting with another, then equal and opposite forces act on each object. So no force acts alone. When you exert a force on something, it is exerting the identical force back on you.

The first and second laws deal with the consequences of the forces that act on an object. The first law says that in the absence of a net force on an object, it simply continues doing whatever it was already doing. If it is at rest, it will remain at rest. If it is in motion, it will continue with that same motion - at constant speed and in the direction it was already traveling.

The second law says what happens if there is a net force on the object. In that case, the object accelerates - either by changing its speed, its direction, or both - in proportion and in the direction of the net force that acts on it. The amount of acceleration depends the object’s mass. That is, the larger the mass the smaller the acceleration for a given net force. The first and second laws can be summarized in the mathematical expression

F = ma

where F is the vector sum of all the forces that act on the object at any given moment (i.e., the net force), m is the mass of the object, and a is the acceleration of the object due to the net force at that moment - and is always in the same direction of the net force.

And notice that in a way, the first law is then “contained” within the second. That is, if the net force is zero on an object, then so is the acceleration. That is, either the object is (still) at rest or, if already in motion, the velocity didn’t change, in either case, the acceleration was zero.

Research indicate that men and women of different races expectationz regarding to gender roles. Which of these statements regard

Ilia_Sergeevich [38]

Answer:

Asian American women are more likely than Asian American men to value egalitarian roles for men and women.

Explanation:

Gender biased has made the environment have different races expectation regarding to gender role.

A socialist feminine (Anita) believes that the oppression of women is based on the capitalist economy.

Parent influence an individuals on their lives socialization.

Some expectations of gender expectation.

1. Men are expected to gain more income, power, and social standing than females.

2. Using biological determinism, it shows that women are more hormonal and men are more aggressive.

3. Few percent of women are in the paid labor force while, large percent of men are in the paid labor force.

4. There is occupational segregation and this why women make up 97% of secretaries and 95% of child-care workers.

5. It is believed that women live longer than men, and this might be due to the stress the man has gone through during is life.

6. In general, men and women differ physically from but women have greater endurance than men.

There should be gender equality because *The Equal Pay Act of 1963" says that men and women receive equal pay for equal work.

Sexual harassment is a form of overt discrimination that has a negative impact on women's.

But today, both men and women say it is not fair for men to be the sole decision maker in the household.

Research on the impact of peer relationships on socialization have found that

1. for boys and girls peers reinforce age and racial norms as well as gender expectations.

2. gender norms are applied more strictly to boys than to girls.

3. homophobia serves to reinforce gender norms.

An enormous thunderstorm covers Dallas-Ft. Worth. Your best friend Clark is a storm chaser and heads to the center of the storm

Rus_ich [418]

Answer:

t = 0.437 s

Explanation:

The speed of sound is a constant that is worth v = 343 m / s

v = d / t

t = d / v

the time it takes for the sound to reach Clark at d = 150 m is

t = 150/343

t = 0.437 s

This same sound takes much longer to reach you

t₂ = 127 10³/343

t₂ = 370 s

What potential difference is required to cause 4.00 a to flow through a resistance of 330 ω?

Alisiya [41]

We can solve the problem by using Ohm's law, which states that an Ohmic conductor the following relationship holds:
$\Delta V = I R$
where
$\Delta V$ is the potential difference applied to the resistor
I is the current flowing through it
R is the resistance

In our problem, I=4.00 A and $R=330 \omega$ , so the potential difference is
$\Delta V = IR=(4.00 A)(330 \omega)=1320 V$
