Answer:
0.012-m
Explanation:
∆L = α × Lo × (T-To)
α is the coefficient of linear expansion = 12 × 10-6 K-1
Lo = Initial length = 25-m
∆L = Change in length
(T-To) = 40 K
∆L = 12 × 10-6 × 25 × 40
∆L = 0.012-m
Answer:
Well first for criteria think what would the rover need in order to sustain itself on Venus. And for constraints think of anything that could possibly affect the rover( ex: gasses, active volcanoes)
Explanation:
Criteria: Make the rover self sustainable, and allow the rover to have a mission on Venus( ex: collect rock samples)
Constraints, as I mentioned above gasses, and active volcanoes.
I hope this helps! :)
Answer:
$ 57,272.73
Explanation:
Create a lengthy equation to convert the units you are given to the units you need to answer the question.
Your starting with gallons and pounds and you need your answer to be in Dollars.
$ 12.00 1 kg 7.0 lb 1500 gal
------------ X ----------- X ------------ X -------------- = $ 57,272.73
1 kg 2.2 lb 1 gal 1
The work needed if a force of 3N is used to move a table 25 metres is 75Nm (joules).
<h3>How to calculate work done?</h3>
Work is a measure of energy expended in moving an object. This means that no work is done if the object does not move.
Force is a physical quantity that denotes the ability to push, pull, twist or accelerate a body and which has a direction and is measured in Newtons.
Work done on an object can be calculated by multiplying the force applied to move the object by the distance the object moves as follows:
Work done = Force (N) × distance (m)
According to this question, a force of 3 Newtons is used to move a table over a distance of 25 meters. The work done on the table can be calculated as follows;
W = 3N × 25metres
W = 75Nm
Therefore, 75Nm is the work done on the table.
