Answer: A- It would increase

Explanation:

According to the law of universal gravitation:

F=G\frac{m_{1}m_{2}}{r^2}  

Where:  

F is the module of the attraction force exerted between both objects

G is the universal gravitation constant.  

m_{1} and m_{2} are the masses of both objects  

r is the distance between both objects

As we can see, the gravity force is directly proportional to the mass of the bodies or objects and inversely proportional to the square of the distance that separates them.

In other words:

<h2>If we decrease the distance between both objects, the gravitational force between them will increase.  </h2>

A 91.1 kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.73 r
KIM [24]

Answer:

\omega_f = 1.08 rad/s

Explanation:

As we know that there is no external torque on the system of platform, banana and the monkey

so the angular momentum of the system will remains conserved

so here we can say

L_i = L_f

I_o\omega = (I_o + m_1r_1^2 + m_2r_2^2)\omega_f

here we know that

I_o = \frac{1}{2}mR^2

I_o = \frac{1}{2}(91.1)(1.61)^2 = 118.1 kg m^2

m_1 = 9.41 kg

r_1 = \frac{4}{5}(1.61) = 1.29 m

m_2 = 21.1 kg

Now from above equation

118.1(1.73) = (118.1 + 9.41(1.29^2) + 21.1(1.61^2))\omega_f

118.1(1.73) = 188.45\omega_f

\omega_f = 1.08 rad/s

Displacement vectors of 4 km north, 2 km south, 5 km north, and 5 km south combine to a total displacement of
valentinak56 [21]

south = -(north)

Displacement = (4 km north) + (2 km south) + (5 km north) + (5 km south)

Displacement = (4 km north) - (2 km north) + (5 km north) - (5 km north)

Displacement = (4 - 2 + 5 - 5) km north

<u>Displacement = 2 km north </u>

If you weigh 150 lbs. on the surface of Earth, how much would you weigh on Venus? On Mars?
Ghella [55]

Answer:

weight on Venus =  604.15 N

weight on Venus = 252.01 N

Explanation:

Given:

Weight on the earth , W = 150 lbs

now,

1 lbs = 4.45 N

thus,

W = 150 × 4.45  = 667.5 N

now, mass on the earth, m = 667.5/9.8 = 68.11 kg

now,

⇒ weight on Venus,

the acceleration due to   gravity on venus = 8.87 m/s²

thus,

weight on Venus = mass × acceleration due to   gravity on venus

or

weight on Venus = 68.11 × 8.87 = 604.15 N

⇒ weight on mars,

the acceleration due to   gravity on mars = 3.70 m/s²

thus,

weight on Venus = mass × acceleration due to   gravity on venus

or

weight on Venus = 68.11 × 3.70 = 252.01 N
