Explanation:
Given that, you are taking a picture of a giraffe that is standing far away from you. The image is just too small, so you swap the 60-mm-focal-length lens in your camera for a 960 mm telephoto lens such that,
We need to find the the factor with which the size of the image increases. It can be calculated by taking ratios of both
So,
So, the size of image increases by a factor of 16. Hence, this is the required solution.
it is true. the trajectory reaches the value of zero at the top
In a projectile, the horizontal acceleration is zero. The velocity remains constant at all times. However, the <u>vertical acceleration</u> is -9.81m/s^2.
Hope this helps!
0.000006kgm/s
Explanation:
Given parameters:
Mass = 0.01g
Velocity = 0.6m/s
Unknown:
Momentum = ?
Solution:
The momentum of a body is the product of its mass and velocity. It is subject to the impact a body in motion will have .
Momentum = mass x velocity
The unit is in kgm/s
We need to convert the mass to kilograms:
1000g = 1kg
0.01g = x kg ; 0.00001kg
Input the parameter:
Momentum = 0.00001 x 0.6 = 0.000006kgm/s
