Answer:
15 N
Explanation:
According to Newton's third law of motion, to every action, there is an equal and opposite reaction. This reaction is equal in magnitude to the force acting but in an opposite direction.
Now, if the book weighs 15 N, an opposite equal force will be: N = -15 N
But the magnitude of this will be the absolute value which is 15N.
Answer:
Modern racism
Explanation:
Modern racism emanates from an aggressive prejudicial behavior to a more subtle prejudicial behavior. This subtle prejudicial behavior advanced to a degree that is much more difficult to see, yet is regarded as more severe. The modern form of racism is the workplace. Although many companies promise an equal opportunity, there is little doubt that everyone is treated equally within their place of work. Subtle, modern racism is believed to create an image that seems more politically correct. The politically correct way to discriminate is through a "polite" form of racism. In the past racism was easily defined and institutional
Modern racism is among the most widespread forms of verbally expressed negative racial attitudes in the United States .
Answer:

Explanation:
We can use the conservation of momentum. The initial momentum is equal to the final momentum:
x-coordinate

(1)
y-coordinate

(2)
We can divide equations (2) and (1):



I hope it helps you!
First we have to find out the gravity on that planet. We use Newton second equation of motion. It is given as,
s = ut +(gt^2)/2
Distance s = 25m
Time t = 5 s
Velocity u = 0
By putting these values,
25 = 1/2.g.(5)²
g = 2
So the gravity on that planet is 2. Lets find out the weight of the astronaut.
Mass of the astronaut on earth m = 80 kg
Weight of astronaut on earth W = mg = (80)(9.8) = 784 N
Weight of astronaut on earth like planet = (80)(2) = 160 N
x = 160N
