Explorers on a planet with a thin atmosphere want to measure the acceleration of gravity at its surface. So they use a spring gu

Murljashka [212]

Answer:

The value of $g_s$ is $g_s=\frac{30}{21} \:\frac{m}{s^2}$ .

Step-by-step explanation:

We know that the position function is given by

$s(t)=30t-\frac{g_s}{2} t^2$

Velocity is defined as the rate of change of position. Therefore,

$v(t)=\frac{d}{dt}(s(t))$

So, the velocity function is

$v(t)=\frac{d}{dt}(s(t))\\\\v(t)=\frac{d}{dt}(30t-\frac{g_s}{2} t^2)\\\\\mathrm{Apply\:the\:Sum/Difference\:Rule}:\quad \left(f\pm g\right)'=f\:'\pm g'\\\\v(t)=\frac{d}{dt}\left(30t\right)-\frac{d}{dt}\left(\frac{g_s}{2}t^2\right)\\\\v(t)=30-g_st$

When a body reaches a vertical velocity of zero, this is the maximum height of the body and then gravity will take over and accelerate the object downward. Thus,

$v(t)=30-g_st=0\\\\g_s=\frac{30}{t}$

We know that the ball bearing reaches its maximum height 21 seconds after being launched (t = 21 s).

So, the value of $g_s$ is $g_s=\frac{30}{21} \:\frac{m}{s^2}$ .

Doors for the small cabinets are 17.5 inches long. Doors for the large cabinets are 2.7 times as long as the doors for the small

AleksAgata [21]

Answer:

3 large doors

Step-by-step explanation:

Given

$Board = 12ft$

Represent small door with S and large with L

$S = 17.5\ in$

From the question, we understand that;

$L = 2.7 * S$

So, we have that

$L = 2.7 * 17.5\ in$

$L = 47.25\ in$

Required

Determine the number of Large doors that can be cut from the board

To do this, we simply divide the size of the board by the size of the large cabinet

i.e.

$Number = \frac{Board}{L}$

$Number = \frac{12\ ft}{47.25\ in}$

Convert feet to inches

$Number = \frac{12 * 12\ in}{47.25\ in}$

$Number = \frac{144\ in}{47.25\ in}$

$Number = 3.04761904762$

Get the integer part of the decimal

$Number = 3$

Hence:

3 large doors can be gotten from the board

I WILL GIVE BRAINLIEST!! I really need help with this question.

Annette [7]

Answer: x = 70, y = 110, z = 85

Step-by-step explanation:

If BE = CD, then using corresponding angles (are equal), x = 70

If x = 70, then 70+y = 180 (angles on a straight line)

y = 110

And z = 85 (corresponding angles again): angle ABE = angle ACD

3. If Earth was 10 times farther away from the sun than it is now, which planet would it be closest to? (Assume all the planets

Soloha48 [4]

The earth is 93 million miles away from the sun. 93 million times 10 is 930,000,000 away. Mars is currently 141.6 million miles from the sun. Assuming the planets were in a straight line you would subtract from 141.6 million miles the 93 million miles so that would put us within 48,600,000 miles of Mars. So the answer is we would be closest to Mars.
