A space vehicle accelerates uniformly from 85 m/s at t = 0 to 164 m/s at t = 10.0 s .How far did it move between t = 2.0 s and t

= 6.0 s ?

Explanation:

Given that,

Initial speed of the vehicle, u = 85 m/s

Final speed of the vehicle, v = 164 m/s

Time, t = 10 s

Firstly, we will find the acceleration of the vehicle using first equation of motion as :

a=\dfrac{v-u}{t}

a=\dfrac{164-85}{10}

a=7.9\ m/s^2

Distance covered by the vehicle at t = 2 s is :

s_1=ut+\dfrac{1}{2}at^2

s_1=85(2)+\dfrac{1}{2}\times 85\times (2)^2

s_1=340\ m

Distance covered by the vehicle at t = 6 s is :

s_2=ut+\dfrac{1}{2}at^2

s_2=85(6)+\dfrac{1}{2}\times 85\times (6)^2

s_2=2040\ m

So, the distance between t = 2 s to t = 6 s is :

s=s_2-s_1

s=2040-340

s = 1700 meters

Hence, this is the required solution.

First, we have a change in the velocity from 85 to 164 m/s in 10 sec.

Then, we calculate the <u>acceleration </u>as:

a=\frac{v_{f}-v_{i} }{t} =\frac{164-85}{10}=7.9 m/s^2

Hence we need to calculate the velocity of the space vehicle at t = 2 sec using the first equation of motion:

v_{f}=v_{i}+at=85+7.9*2=100.8m/s

Then, using the second equation of motion to calculate the distance:

d=v_{i}  t+\frac{1}{2}at^2

d=100.8*2+\frac{1}{2}*7.9*(2)^2=217.4m

A fixed electric space heater wired by a cable with an ampacity of 30 A should draw a maximum current of A. 30 A. B. 24 A. C. 15
Nookie1986 [14]

Answer: The correct answer is option (A).

Explanation

Ampacity is defined as the maximum amount of the current carried by the conductor continuously without exceeding its temperature rating.

The ampacity of the wire of the heater is 30 A .And this means that wire is capable of conducting current of maximum amount of 30 Ampere through it without exceeding its temperature rating.

Hence, the correct answer is option is (A).

Why are the temperatures on each of the other terrestrial planets more extreme than earth?
netineya [11]
Other terrestrial planets have more extreme temperatures mainly because of their atmospheres
Explanation:
for example the atmosphere of Venus is composed mainly of carbon dioxide, this carbon dioxide traps the heat or energy from the sun and makes the planet have higher temperatures. where on mars the atmosphere is very thin so it takes in lots of heat and doesn't keep it in very well so it gets very hot and very cold

Could the earth have decreased when the astroid hit
Anarel [89]

If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically..
