Answer:

15mph

Explanation:

Because you've already done distance and time. Speed=distance divided by time. so it would be 300 divided by 20 giving you 15.

Answer:

B and D

Explanation:

Given parameters:

Distance of Pigeon Forge = 58.25miles

Speed  = 62.5mile/hr

Unknown:

Time it will take Billy to get to Pigeon Forge = ?

Solution:

Speed is a physical quantity and it is the rate of change of distance with time.

       Speed  = [tex]\frac{distance}{time}[/tex]

     Now let us input the parameters and find the time;

               62.5  = [tex]\frac{58.25}{t}[/tex]

              58.25  = 62.5t

                   t = [tex]\frac{58.25}{62.5}[/tex]   = 0.93hrs

Time taken for him to get there is 0.93hrs

Answer:

The difference in the amount of energy transferred by the two bulbs is 1200 J.

Explanation:

The energy transferred by the two lightbulbs can be calculated with the given equation:

[tex] E = P*t [/tex]

Where P is the power and t is the time

For the 60 W lightbulb:

[tex] E_{60} = P*t = 60 W*30 s = 1800 J [/tex]

For the 100 W lightbulb:

[tex] E_{100} = P*t = 100 W*30 s = 3000 J [/tex]

Hence, the difference in the amount of energy transferred is:

[tex] E_{t} = E_{100} - E_{60} = 3000 J - 1800 J = 1200 J [/tex]

Therefore, the difference in the amount of energy transferred by the two bulbs is 1200 J.

I hope it helps you!

The difference in the amount of energy transferred by the two bulbs during this time is 1200 J.

We know that

E = P*t

Here

P means the power and T means the time

So for 60W lightbulb, the energy should be

= 60*30

= 1800J

For 100 W, the energy should be

= 100*30

= 3000 J

So, the difference is

= 3000 -1800

= 1200 J

hence, The difference in the amount of energy transferred by the two bulbs during this time is 1200 J.

Answer:

A.125

Explanation:

Its correct on Schoology.

Answer:

The height is 1.20 m above the window.

Explanation:

Given that,

Height of window = 1.10 m

Time = 0.190 sec

We need to calculate the velocity

Using equation of motion

[tex]s=ut+\dfrac{1}{2}gt^2[/tex]

Put the value into the formula

[tex]1.10=u\times0.190+\dfrac{1}{2}\times9.8\times(0.190)^2[/tex]

[tex]1.10=u\times0.190+0.17689[/tex]

[tex]u=\dfrac{1.10-0.17689}{0.190}[/tex]

[tex]u=4.85\ m/s[/tex]

We need to calculate the height

Using equation of motion

[tex]v^2=u^2+2gh[/tex]

Put the value into the formula

[tex](4.85)^2=0+2\times9.8\times h[/tex]

[tex]h=\dfrac{(4.85)^2}{2\times9.8}[/tex]

[tex]h=1.20\ m[/tex]

Hence, The height is 1.20 m above the window.

Answer:

The stone thrown upward lands farther away from the building.

Explanation:

Given that,

Angle = 30° above the horizontal

Speed = 18.0 m/s

Angle = 30° below the horizontal

Suppose, Which stone lands farther away from the building ?

We need to find which stone lands farther away from the building

Using formula of range

[tex]R=v_{x}t[/tex]

The horizontal velocity for the both stones is equal but the time will be different.

The time of stone thrown upward will be greater than that of downward.

Hence, The stone thrown upward lands farther away from the building.

HOW NEWTON'S LAWS RELATE TO REAL WORLD LIFE EXPERIENCE

Newton's law are very important because they tie into almost everything we see in everyday life. These laws tell us exactly how things move or sit still, like why you don't float out of bed or fall through the floor of your house. Newton's laws control how cars work, how water flows, how buildings don't fall down, and basically how everything around us moves.

EXAMPLE OF NEWTON'S LAW:

° First Law: Inertia

°Second Law: Force and Acceleration

°Third Law: Action and Reaction

HOW NEWTON'S LAW RELATE TO REAL LIFE EXPERIENCE

FIRST LAW (INERTIA) :

If you throw a rock straight up, it will not vary from its direction. Inertia enables ice skaters to glide on the ice in a straight line. If the wind is blowing, a tree's branches are moving. A piece of ripe fruit that falls from the tree will fall in the direction the wind is moving because of inertia.

SECOND LAW (FORCE AND ACCELERATION) :

The use of force in our everyday life is very common. We use force to walk on the road, to lift the objects, to throw a cricket ball, or to move a given body by some particular speed or direction. We are very familiar with the various effects of force. We can exert pull and push. And also When the car slows down. When you fall off a bridge. The car turning at the corner is an example of acceleration because the direction is changing. The quicker the turns, the greater the acceleration.

THIRD LAW (ACTION AND REACTION) :

For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers too apply Newton's third law when designing rockets and other projectile devices.
