PLEASE HELP ASAP ! 37 POINTS !!!!

Maksim231197 [3]

Answer:

3. all of the above

4. d=m/v

5. gas has well separated particles with no particular arrangement

liquid has particles close together but still with no particular arrangement

and solid has particles that are tightly packed, usually in a regular pattern

6. (idk what number it is but)

the density of the rock is 2.4 g/ml

d=m/v so d=12/v according to the question the mass is 12

to find volume subtract 20-15 because before the rock was 15 and after the rock was 20, so then you get 5 for volume

d=12/5 and when you calculate that, you would get 2.4g/ml ; hope this helped :-)

A force does work on an object if a component of the force is

IrinaK [193]

Answer:

A force does work on an object if a component of the force is parallel to the displacement of the object.

Explanation:

Work, a measurement of energy is said to be done when a force applied to an object results in the movement of that object to a certain distance and direction. Force is the act of push or pulls occurs on an object as a result of the interaction between that object with another one and displacement is the distance and direction covered by that object as a result of the force applied on it.

The work done (W) by a constant force (F) is equal to the product of the force in the direction of displacement of the object and the distance (d) moved by the object i.e., W = F * d.

The angle between the displacement and the force is θ, then the work done, W = Fd cos θ ........ (1)

Positive work - Force acts in the same direction with respect to the displacement of the object. Here, θ is zero, so cos θ i.e., cos 0 is 1. Therefore, from the equation (1), W = Fd (i.e., work done by the force is positive).

Negative work - Force acts in the opposite direction with respect to the displacement of the object. Here, θ is 180°, so cos θ i.e., cos 180° is -1. Therefore, from the equation (1), W = -Fd (i.e., work done by the force is negative).

If a force is applied to an object and it does not move, then the work done is zero i.e., W = F * 0 = 0. Also, if the force and displacement are at right angle to each other, then θ is 90°. Therefore, from the equation (1), W = 0 since cos 90° is zero.

The mass of a proton is 1833 times larger than the mass of an electron. When a proton an electron interact with each other the o

Ad libitum [116K]

B. Exactly the same as the electric force of the electron on the proton.

<u>Explanation:</u>

Even if the mass of proton is increased or decreased, the force between electron and proton will remain the same because force is dependent on the charge of the object and distance between them. The force between the charges is independent of their masses. So, even if the mass of a proton is 1833 times larger than the mass of an electron, the force between them will be same.

According to Coulomb's law:

$F = k\frac{q_1q_2}{r^2}$

where,

F is the force

q₁ and q₂ are the charges

r is the distance between the charges
