Inital velocity of the jet (v) = 24 m/s
final velocity (u) = 0
time taken (t) = 1.6 s
acceleration(a) = (final velocity- inital velocity)/ time
= (0 - 24) /1.6
= -24/ 1.6
= -15
so,
the acceleration was - 15 m/s^2
Since the law of gravitation is an inverse square law if you
quadruple the radius the f will drop by a factor of 16 SO the object would
weigh 200/16 = 12.5N
In other words, as the distance, or radius, quadruples the
weight becomes 1/16 of the original weight. Just plug in 4 for r and when you
square it you get 16. The numerator is 1 so that is how the weight becomes
1/16.
Medical imaging is the process in which you create a model or a visual representation of the human body and functions for medical reasons.
Answer:
1 gallon = 3.8 liters rounded to the nearest tenth.
Explanation:
1 gallon = 3.785 litres.
We have to round this in to nearest tenths, nearest tenth means number of figures after decimal = 1.
Here last digit is 5 so we have to add 1 to previous digit.
So, 3.785 rounded will become 3.79
For 3.79 the last digit is 9 so we have to add 1 to previous digit.
So, 3.79 rounded will become 3.8
3.785 liters rounded to the nearest tenth is 3.8 liters.
1 gallon = 3.8 liters rounded to the nearest tenth.
Answer: 24.4 degrees to the vertical
Explanation:
Vertical component of raindrop speed = 11m/s
Horizontal component of wind = 5m/s
In this case, all we have to do is to use trigonometric ratios of angles to sides as in a triangle
Doing this, we see that
tan (theta) = 5/11
(Where theta is the angle made with the vertical by the rain after impact)
Tan being opposite/adjacent
Arc sin (5/11) gives us 24.44 degrees to the vertical
