A new planet is discovered that has twice the Earth's mass and twice the Earth's radius. On the surface of this new planet a per

kirza4 [7]

Answer:

option B

Explanation:

Radius of new planet,R' = 2R

Mass of the earth, M' = 2 M

R and M is the Radius and Mass of the earth.

Weight of the person on earth = 500 N

Weight of the person in the new planet = ?

We know acceleration due to gravity is calculated by using formula

$g = \dfrac{GM}{R^2}$

now, acceleration due to gravity on the new planet

$g' = \dfrac{GM'}{R'^2}$

$g' = \dfrac{G(2M)}{(2R)^2}$

$g' =\dfrac{1}{2} \dfrac{GM}{R^2}$

$g' =\dfrac{g}{2}$

here acceleration due to gravity is half in new planet, so weight will also be half on the new planet.

Weight on the new plane is equal to $\dfrac{500}{2}$ = 250 N

correct answer is option B

A hockey puck slides across the ice with an initial velocity of 7.3 m/s .It has a decleration of 1.1 m/s and is traveling toward

sashaice [31]

Answer:

t = 6.63 s

Explanation:

Given that,

Initial velocity of the puck, u = 7.3 m/s

Deacceleration of the puck, a = -1.1 m/s²

Distance traveled, d = 5 m

We need to find the time the goalie have to stop the puck. Using equation of motion.

v = u +at

v = 0 (stops)

So,

$u=-at\\\\t=\dfrac{u}{-a}\\\\t=\dfrac{7.3}{-(-1.1)}\\\\t=6.63\ s$

So, the required time is 6.63 seconds.

HURRY!!!!! Which change of state is shown into the model?

nadezda [96]

Option (B) is correct. The process shown in the model is the process of DEPOSITION.

Explanation:

The first container shows the molecules of the substance present inside it at a fairly large distance from one another whereas the second container, the molecules of the substance are very close to each other.

This shows that the substance in the first container is gaseous in nature whereas the substance in the second container is solid in nature as its molecules are closely packed.

Therefore, it shows the phase transition of a substance from gaseous sate to the solid state. The process of conversion of a gas directly into a solid is termed as deposition. This process is the opposite of the Sublimation in which the solid gets directly converted into a gas. Thus, the process is also termed as desublimation.

Thus, Option (B) is correct. The process shown in the model is the process of DEPOSITION.
