Answer:
The coefficient of linear expansion \°C
Explanation:
Given initial temperature °C
And final temperature °C
Initial length
Final length
We have to find the coefficient of linear expansion
The coefficient of linear expansion is defined as the change in length per unit original length divide by the change in temperature.
So, \°C
Answer:
I think is 3 I am not sure
Answer:
W = 7000 J
Explanation:
To solve this problem we use that the speed of the bicycle is constant, therefore its acceleration is zero
F -fr = 0
F = fr
where F is the force applied by the child
Work is defined by
W = F. x
W = F x cos θ
in this case the child's force is parallel to the movement, therefore the angle is zero and cos 0 = 1
let's calculate
W = 35 200
W = 7000 J
Answer:
Final image size is increasing and it is moving away from the focus on the other side
Explanation:
As the object is moving towards the focus of the lens
Then the size of image will start increasing and also the image is formed between focus and double focus point
So we can say that size of image will start increases and the position of image is start moving away from the focus on the other side of the lens
In both the case the image must be Real and diminished and its size is start increasing due to the formula
[tex]M = \frac{d_i}{d_o}[/tex
So here present
Final image size is increasing and it is moving away from the focus on the other side
the answer is a) 0.00235 because 1/425=0.00235. hope I helped!
