An object is thrown horizontally from the open
window of a building. If the initial speed of the
object is 20 m/s and it hits the ground 2.0 s later,
from what height was it thrown? (Neglect air
resistance and assume the ground is level.)
Initial vertical velocity = 0
formula: s = ut + (1/2)*g*t^2
s = 0 + 1/2*9.8*2^2
s = 9.8*2 = 19.6 m

Which statement is true about how objects appear to bend that are partially submerged in water?They appear to bend at the surface due to reflection.
They appear to bend at the surface due to refraction.
They appear to bend at the surface due to diffraction.
They appear to bend at the surface due to interference

Answers

The correct answer to the question is: B) They appear to bend at the surface due to refraction.

EXPLANATION:

When light moves from optical rarer medium to optical denser medium, the light rays are bent towards the normal at the point of incidence on the refracting surface. If the order is changed, then the way will be away from the normal.

This property of light is known as refraction which is due to the fact that light has different velocities in different media.

As per the question, the object appears to be bent when it is submerged in water. Actually the object is not bent. Its the light from object which is bent at the air-water interference.

Hence, the correct answer of this question is refraction.

Answer:

answer is b

Explanation:

The horsepower (hp) that a shaft can safely transmit varies jointly with its speed, in revolutions per minute (rpm), and the cube of the diameter. If the shaft of a certain material 3 inches in diameter can transmit 46 hp at 100 rpm, what must the diameter be in order to transmit 74 hp at 175 rpm?

Answers

Answer:

diameter ≅ 3 inches

Explanation:

$HP=k*s*d^(3)$

Use a constant factor, k

Let Hp = horsepower

Let s = speed in rpm

Let d = diameter in inches

to find constant k, using

Hp=46

S=100

d=3 in

$46=k*100*3^(3) \n\n46=k*100*27\n46=2700k\nk=(46)/(2700) \nk=0.017\n\n$

To find diameter when;

Hp=74

S=175

k=0.017

d=d inches

$74=0.017*175*d^(3) \n\n74=2.975*d^3\nd^3=(74)/(2.975) \nd=\sqrt[3]{24.87} \nd=2.9 inches\n\n$ d≅ 3 inches

What determines the composition of a rock

Answers

Is determined by the percent of constituent of minerals and elements contained within it.

Composition of a rock is determined by the percent of constituent of minerals and elements contained within it.

Explanation:

The composition of a rock is decided by the % of the constituent minerals and components contained inside it.

The minerals that form up rocks have outlined chemical compositions and rigid atomic structures. once daylight strikes the rock's surface, the composition and atomic structure of the various minerals management the wavelengths they absorb or replicate.

Which alternative energy source would be expected to be the least dependent upon the weather?a. wind power
b. solar power
c. geothermal power
d. none of the above

Answers

Answer;

C. geothermal power

Explanation;

Geothermal power is considered to be a sustainable, renewable source of energy because the heat extraction is small compared with the Earth's heat content. It depends the least on weather.

Geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Of the three sources listed, geothermal energy
is the least dependent on the weather.
