Answer:

The object with the greater mass will have the greater momentum

Explanation:

The momentum of an object with mass m, moving with velocity , is given by the formula

M = mv

Since both objects have the same velocity v, it is clear that the object with the bigger mass will have the greater momentum

Dafna1 [17]

Answer:

From left = 1.2L

From back = 0.9L

Explanation:

5 x = 3(L-X) + 2(2L-X)

X = 0.7L

Distance from left = 1.2L

7y = 2(L-X)+1(2L-x)

Y = 0.4L

Distance from back = 0.9L

The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.

grandymaker [24]

Answer:

True.

Explanation:

The given statement is true that the law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.

According to this law, the forces between two masses can be calculated by the product of their masses and divided by the square of the distance between them. Mathematically, it can be written as :

$F=\dfrac{Gm_1m_2}{r^2}$

G is universal gravitational constant

Hence, the given statement is true.

It is proposed that a spaceship might be propelled in the solar system by radiation pressure, using a large sail made of foil. W

Anvisha [2.4K]

Answer:

962291.57928 m²

Explanation:

$P_r$ = Pressure = $2\dfrac{I}{c}$ (full reflection)

I = Intensity = $\dfrac{P}{A}=\dfrac{P}{4\pi r^2}$

P = Power = $3.9\times 10^{26}\ W$

c = Speed of light = $3\times 10^8\ m/s$

M = Mass of Sun = $1.99\times 10^{30}\ kg$

m = Mass of ship = 1500 kg

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

Force of radiation is given by

$F_r=P_rA\\\Rightarrow F_r=2\dfrac{I}{c}\times A\\\Rightarrow F_r=2\dfrac{P}{4\pi r^2c} A$

This force will balance the gravitational force as stated in the question

$\dfrac{GMm}{r^2}=2\dfrac{P}{4\pi r^2c} A\\\Rightarrow A=\dfrac{4\pi cGMm}{2P}\\\Rightarrow A=\dfrac{4\times \pi\times 3\times 10^8\times 6.67\times 10^{-11}\times 1.99\times 10^{30}\times 1500}{2\times 3.9\times 10^{26}}\\\Rightarrow A=962291.57928\ m^2$

The area of the must be 962291.57928 m²
