Question

Identify each statement as either true or false.
1.To find the mass of an object, multiply
the weight of the object and gravity.
2.If it is high tide in one place on Earth,
the place exactly opposite to it will have
a low tide.
3.The mass of an object on Jupiter is
greater than its mass on Eart
4.The Sun, along with the entire solar
system, moves around the galaxy.
5.Without gravity, there would be no
atmosphere surrounding Earth.

Answer 1

1 is false. Weigth = mass x gravity not Weight x gravity
3 is false. weight is different not mass
4 i think true

Answer 2

Answer:

1.False

2.False

3. False

4.True

5. True

Explanation:

1. Its false because

weight of an object= mass x gravity

therefore,

$mass= \frac{weight}{gravity}$

2. Its  False

water which is close to moon get attracted by The Moon. Therefore the water of the sea which is in front of the Moon bulges towards it and due to inertia water on the opposite side also bulges.

3. Its false

Gravity on jupiter is $24.79 \frac{m}{s^{2}}$

and Gravity on earth is $9.8 \frac{m}{s^{2}}$

we know that mass of an object is given as,

$mass= \frac{weight}{gravity}$

It means mass is inversely proportional to gravity, since gravity on jupiter is greater than the gravity on earth therefore the mass of an object  earth is greater than the mass on earth.

4. Its true

The Sun, along with the entire solar  system, moves around the galaxy with the a speed of $828\times 10^3 \frac{km}{hr}$ in a circular orbit.

5. Its True

Without gravity there would be no atmosphere surrounding earth because without gravity everything including water will move into outer space.
