Answer: the answer is D

Explanation:

When we look at an object and see its color, we are seeing all of the light that reflects off of that object. Red objects reflect red light, green objects reflect green light, and so on. But what happens to the rest of the colors that hit that object? They get absorbed!

A rock is dropped from the top of a tall building. The rock's displacement in the last second before it hits the ground is 46 %

olasank [31]

Answer:

height is 69.68 m

Explanation:

given data

before it hits the ground = 46 % of entire distance

to find out

the height

solution

we know here acceleration and displacement that is

d = (0.5)gt² ..............1

here d is distance and g is acceleration and t is time

so when object falling it will be

h = 4.9 t² ....................2

and in 1st part of question

we have (100% - 46% ) = 54 %

so falling objects will be there

0.54 h = 4.9 (t-1)² ...................3

now we have 2 equation with unknown

we equate both equation

1st equation already solve for h

substitute h in the second equation and find t

0.54 × 4.9 t² = 4.9 (t-1)²

t = 0.576 s and 3.771 s

we use here 3.771 s because 0.576 s is useless displacement in the last second before it hits the ground is 46 % of the entire distance it falls

so take t = 3.771 s

then h from equation 2

h = 4.9 t²

h = 4.9 (3.771)²

h = 69.68 m

so height is 69.68 m

A physical science test book has a mass of 2.2 kg what is the weight on mars??? please help

Nastasia [14]

Weight = (mass) x (gravity)
= (2.2 kg) x (3.7 m/s^2)

= 8.1 newtons. (about 1.84 pounds)

Answer:

Solution given:

any three applications of electromagnetic waves are:

Used for cooking purpose in microwave.
Used in RADAR system for aircraft navigation.
Used in communication.

Solution given;

power [P]=100W

Current [I]=5A.

Voltage [V]=?

we have

P=IV

100=5*V

V= $\frac{100}{5}$ =20V

the voltage of the battery used in the car is 20V.
