What is the force of gravity between Jupiter and Saturn? The mass of Jupiter is 6.4 x 1024 kg. The mass of
kogti [31]

Given :

The mass of Jupiter is 6.4 x 1024 kg. The mass of  Saturn is 5.7 x 1026 kg. The distance between Jupiter and Saturn is 6.52 x 10 11 m.

To Find :

The force of gravity between Jupiter and Saturn .

Solution :

We know force of attraction between two bodies is given by :

F = \dfrac{Gm_Jm_S}{\\d^2}

Here, G = gravitational constant = 6.67408 × 10-11 m3 kg-1 s-2 .

Putting all these in given equation, we get :

F=\dfrac{6.67\times10^{-11}\times6.4\times10^{24}\times5.7\times10^{26}}{(6.52\times10^{11})^{2}}

F =  5.72\times 10^{17}\ N

Hence, this is the required solution.

Steven carefully places a 1.65-kg wooden block on a frictionless ramp, so that the block begins to slide down the ramp from rest
nadya68 [22]

Answer:

a. Gravity and c. Spring

Explanation:

Formula for work energy W = \vec{F} \bullet \vec{S} = FScos(\alpha)

whereas F is the force acting on the block, S is the distance traveled, and \alpha is the angle between 2 vectors F and S.

If F is perpendicular to S, then

\alpha = 90^o

cos(\alpha) = cos(90^o) = 0

W = FS*0 = 0

a. Normal force is the reaction force acting from the ramp back on the wooden block. This force is perpendicular to the direction of sliding. Therefore this force would do no work.

b. Gravity is the force acting downward, this would have an angle of 90^o - 58.3^o = 31.7^o degrees so the work is non-zero.

c. Spring force would have the same direction as sliding so the work is non-zero.

d. Friction force would have the same direction as sliding. However, as this is a frictionless ramp, the friction coefficient would be 0. Friction force would also be zero and so as its work.

How could the combustibility of a substance influence how the substances used
Advocard [28]

Answer:

Combustibility is a measure of how easily a substance bursts into flame, through fire or combustion. This is an important property to consider when a substance is used for construction or is being stored. It is also important in processes that produce combustible substances as a by-product.

A body is projected from a point P with an initial speed of 30m/s, at an angle 65° to the horizontal. what is the vertical dista
Mariulka [41]

Answer:

Vx = 30 * cos 65 = 12.7 m/s    initial horizontal speed

Vy = 30 * sin 65 = 27.2 m/s    initial vertical speed

t = 45 / 12.7 = 3.54 s     time to travel horizontal distance of 45 m

h = vy t - 1/2 g t^2      height after time t

h = 27.2 * 3.54 - 1/2 * 9.8 * 3.54^2 = 34.9 m
