Andrew [12]

Answer:

10.2 metres

Explanation:

Given that a ball is projected at an initial speed of 20.0 meter per second making an angle of 45.0 with horizontal. What is the maximum height it will reach?

Solution

To get the maximum height, let us use the formula

V^2 = U^2 sin^2ø - 2gH

At maximum height V = 0

U^2 sin^2ø = 2gH

Substitute all the parameters into the formula

20^2 ( sin 45 )^2 = 2 × 9.8 × H

400 × 0.5 = 19.6 H

Make H the subject of formula

H = 200 / 19.6

H = 10.204 metres.

Therefore, the maximum height reached by the projected ball is 10.2 metres.

Explain why semiconductors, or metalloids, deserve their name.
Marysya12 [62]

Answer:

Because their properties like conductivity, electronic configuration and ionization lies in between the metals and nonmetals.

Explanation:

There are a total of six elements that fall in the category of semiconductors.

Namely these are boron, silicon, germanium, arsenic, antimony, and tellurium.

These elements look like metals i.e. are lustrous but do not conduct electricity  so well like a metal does.

Their chemical behavior falls between that of metals and nonmetals. For example, the pure metalloids form covalent crystals like the nonmetals, but like the metals, they generally do not form mono-atomic anions.

On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 3.70 times as far as he wo
Margarita [4]

Answer:

a)H=84.87 m

b)R=565.27 m

Explanation:

Given that

Speed of ball on earth

U=41.2 m/s

θ=31°

We know that

Maximum height in projectile motion given as

h=\dfrac{U^2sin^2\theta }{2g}

h=\dfrac{41.2^2sin^231}{2\times 9.81}

h=22.94 m

Range in projectile motion given as

r=\dfrac{U^2sin2\theta }{g}

r=\dfrac{41.2^2sin62 }{g}

r=152.77 m

Given that on distance planet ball moves 3.7 times far more as on earth.

So on the distance planet

The maximum height ,H=3.7 h

H= 3.7 x 22.94

H=84.87 m

The range on distance planet

R=3.7 r

R=3.7 x 152.77 m

R=565.27 m
