Question 11(Multiple Choice Worth 3 points)

Physics
1 answer:
melomori [17]3 years ago
8 0

Answer:

Explanation:

The only thing that decreases the gravitational pull between 2 objects is if you<u> increase the distance.</u>

The formula is F = G*m*m/r^2

As r^2 gets larger and G and m1 and m2 remain the same, F has to get smaller because r^2 divides into G*m1*m2

In solar thermal electric generation, the sun’s energy is concentrated by ___ to heat the fluid in a pipe that is used to genera
pishuonlain [190]

Answer:

<u>Mirrors</u>

Explanation:

In Solar thermal power generation system, mirrors are used to collect and focus sunlight  onto a fluid pipe to produce high temperature required to generate electricity.

There are two main components: mirrors capture and focus light onto a receiver. The heat transfer fluid is circulated in the receiver. Steam is produced which is converted to mechanical energy in a turbine. It powers a generator and electricity is produced.

Consider a railroad bridge over a highway. A train passing over the bridge dislodges a loose bolt from the bridge, which proceed
schepotkina [342]

Answer:

12.35m

Explanation:

Hello! To solve this problem we must consider the following:

1. The car moves with constant speed, which means that the distance traveled is equal to the multiplication of time by speed.

X = VT

we solve the equation for time

T=\frac{x}{V} =\frac{27}{17} =1.588s

2. The bolt moves with constant acceleration, with acceleration of 9.81m / s ^ 2, so we could apply the following equation.

note=remember that "a uniformly accelerated motion", means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.

Y= VoT-\frac{1}{2}gt^{2}

where

Vo = Initial speed

=0

T = time

=1.588s

g =gravity=9.8m/s^2

Y =  bridge height

solving

Y= \frac{1}{2}gt^{2}\\Y=(0.5)(9.8)(1.588^2)=12.35m

Water doesn't belong on that list.

If it's removed, then there's a space to add GAS, which does belong.
