1. The diagram shows a satellite traveling in uniform circular motion around the Earth.

FromTheMoon [43]

Answer:

M V R = constant angular momentum is constant because no forces act in the direction of V

Since M (mass) = constant

V R = constant

The force is directed along the gravitational force vector (towards the center of rotation)

Consider an object with weight on the Earth W_earth. The gravity of the Earth is g. If it is moved to another planet with gravit

Mazyrski [523]

Answer:

$W_{Planet} = \frac{W_{Earth}}{g}\times a$

Explanation:

We know that weight of an object on Earth is,

$W_{Earth} = m\times g$

Thus,

$m = \frac{W_{Earth}}{g}$

where,

m = mass of an object, which is constant and is independent of gravity

g = acceleration due to gravity on Earth

On the new planet, gravity = a

Thus the weight of the object on the new planet will be

$W_{Planet} = m\times a$

$W_{Planet} = \frac{W_{Earth}}{g}\times a$

The specific heat of water in its solid phase (ice) is 2090 J/(kg K), while in the liquid phase (water) its specific heat is 419

oee [108]

Answer:

d. 149 ⁰C.

Explanation:

Given;

mass of the block of ice, m = 2 kg

specific heat capacity of the ice, C = 2090 J/(kgK)

initial temperature of the ice, t₁ = -90 ⁰C

heat added to the ice, H = 1,000,000 J

let the final temperature of the ice = t₂

The final temperature of the ice after adding the heat is calculated as follows;

$H = mC_{ice} \Delta t\\\\H = mC_{ice} (t_2 - t_1)\\\\1,000,000 = 2 \times 2090 \times (t_2 - (-90))\\\\1,000,000 = 4,180(t_2 +90)\\\\1,000,000 = 4,180t_2 + 376,200\\\\1,000,000 - 376,200 = 4,180t_2\\\\623,800 = 4,180 t_2\\\\t_2 = \frac{623,800}{4,180} \\\\t_2 = 149 \ ^0C$

Therefore, the new temperature of the water is 149 ⁰C.
