Answer:
c. Moon A is four times as massive as moon B
Explanation:
Let's assume the:
- mass of the object =

- mass of the moon A =

- mass of the moon B =

- distance between the center of masses of the object and moon B =

According to the given condition the object is twice as far from moon A as it is from moon B
- ∴distance between the center of masses of the object and moon B =

<u>As we know, gravitational force of attraction is given by:</u>

<em>According to the condition</em>
Force on m due to
Force on m due to



It would decrease, hope it helps
Answer:
The time taken to reach the maximum height is 3.20 seconds
Explanation:
The given parameters are;
The initial height from which the volcano erupts the lava bomb = 64.4 m
The initial upward velocity of the lava bomb = 31.4 m/s
The acceleration due to gravity, g = 9.8 m/s²
The time it takes the lava bomb to reach its maximum height, t, is given by the following kinematic equation as follows;
v = u - g·t
Where;
v = The final velocity = 0 m/s at maximum height
u = The initial velocity = 31.4 m/s
g = The acceleration due to gravity = 9.8 m/s²
t = The time taken to reach the maximum height
Substituting the values gives;
0 = 31.4 - 9.8 × t
∴ 31.4 = 9.8 × t
t = 31.4/9.8 ≈ 3.204
The time taken to reach the maximum height rounded to three significant figures = t ≈ 3.20 seconds
Despite the risks, Human populations can be found near volcanoes. This can be associated with the availability of which natural resource?
