Answer:
Dog
Explanation:
(Mass)(velocity) > (Mass delta) (velocity delta)
Answer:
Explanation:
The gravitational force acting on the ball, F = 10 N (down) The air resistance acting on the ball, f = 1 N (up) We need to find the magnitude of net force acting on the ball. The net force is given by : F' = 9 N. So, the net force acting on the ball is 9 N in downward direction. Hence, this is the required solution
Answer:
A
Explanation:
The energy of an electromagnetic wave is directly proportional to its frequency, according to the equation:
E = hf
where
h is the Planck constant
f is the frequency
The frequency of a wave is the number of complete cycles per unit of time: in the figures shown, we see that the more we go towards the right, the higher the frequency is (because the wavelength becomes shorter, so the waves makes more complete cycles per second). This means that the more the box is on the right, the higher the frequency: the figure with the box located more on the right is A, so this is also the figure that represents the range of frequencies with most energy.
Answer:
B
Explanation:
i just did it on study island
You probably know that i is x and j is y. So if you put them on a triangle where they should be, you see that you are basically finding the hypotenuse of the triangle. Use Pythagorean theorem, solve for H.
