Answer:
The displacement of the elevator between 8 s and 24 s is 6 m.
Explanation:
Given that,
Initial time = 8 s
Final time = 24 s
We know that,
Displacement :
Displacement is the difference between initial position and final position.
In mathematically,
We need to calculate the displacement
Using formula of displacement
Put the value from graph
Hence, The displacement of the elevator between 8 s and 24 s is 6 m.
A thermal conductor is an item that can conduct thermal energy or temperature, much like a knife.
Metals often feel cool to the touch because the are thermal conductors, storing cool energy making them feel cooler.
Using thermal energy is like taking a knife and warming it up so it can better cut through objects.
Answer:
5.4kgm/s towards the hitter.
Explanation:
Given parameters:
Mass = 0.12kg
Velocity = 45m/s
Unknown:
Momentum of the baseball = ?
Solution:
To solve this problem, we must understand that the momentum of a body is the quantity of motion it possesses.
Momentum = mass x velocity
Now insert the parameters and solve;
Momentum = 0.12 x 45 = 5.4kgm/s towards the hitter.
Answer:
Explanation:
magnification is the ratio of distance of image to distance of object
i.e.
As per the lens equation,
We will calculate the focal length of the mirror
Now for convex mirror only the sign will change
Thus, focal length would be equal to
Plugging this value into lens equation, we get
