you push a block of 50kg with a force of 400 N over a distance of 8m. How much kinetic energy does the box gain?

Answer:

1 / f = 1 / o + 1 / i

1 / image distance + 1 / object distance = 1  focal length

If the object distance is large the image will be at about the focal length

The value of 1 / f is fixed for any one particular lense

As the object distance decreases the image must increase

The above equation can also be written as

o i / (i + o) = f    or i / (i / o + 1)  = f

If for instance o was very large the image would be at the focal length

Answer:

In a building, heat rises. By putting the insulation in the ceiling heat will rise and get trapped at the top and fill up the entire room. The purpose of insulation is to minimize the transmission of heat within the walls, floors, and ceilings. By minimizing the transmission of heat, you not only keep the room warm but you also lower your electricity and heat bill.

Explanation:hey im in 7th grade and even i know that.i sorry but you seem not the smartest.jk thats a good question

Answer:

because there isn't any gravity there

a) V= 13m/s at 24 degrees

X component of velocity Vx= V*cos24 =11.876 m/s

distance =4.2 meter

time =distance/speed =4.2/11.876 =0.3537 s

b) Vertical component of speed = Vy=vsin24=

5.29 m/s

s=ut+0.5at^2 =5.29880.3537-0.5*9.8*0.3537^2

=1.257 m above ground

Answer:

answer 7m/s^2

Explanation:

›»› The Acceleration of jumper = 7 m/s²

Given :

Initial velocity of jumper (u) = 0 m/s

Final velocity of jumper (v) = 10.5 m/s

Time taken by jumper (t) = 1.5 sec

To Find :

Acceleration of jumper (a) = ?

Required Solution :

→ Initial velocity (u) = 0 m/s (because jumper increase from zero)

† From first equation of motion

⇒ v = u + at

⇒ 10.5 = 0 + a × 1.5

⇒ 10.5 = 0 + 1.5a

⇒ 10.5 = 1.5a

⇒ a = 10.5/1.5

⇒ a = 7 m/s²

║Hence, the Acceleration of jumper is 7 m/s².║

\:

Additional Information :

★ First equation of motion :

⪼ v = u + at

Where,

v is the Final velocity in m/s.

u is the Initial velocity in m/s.

a is the Acceleration in m/s².

t is the Time taken in second.

★ Second equation of motion :

⪼ s = ut + ½ at²

Where,

s is the Distance travelled in m.

u is the Initial velocity in m/s.

a is the Acceleration in m/s².

★ Third equation of motion :

⪼ v² = u² + 2as

Where,

v is the Final velocity in m/s.

u is the Initial velocity in m/s.

a is the Acceleration in m/s².

s is the Distance travelled in m.

Answer:

127.4 newtons

Explanation:

Assuming g = 9.8:

F = ma = 13(9.8) = 127.4 N

The force of a 13 Kilogram ball that has been dropped and has fallen for 1 second, then the force offered by the ball would be 127.53 Newtons.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

As given in the problem we have to find the force of a 13-kilogram ball that has been dropped and has fallen for 1 second,

The force of the dropped ball = mass of the ball × acceleration due to gravity

The force of the dropped ball = 13 × 9.81

                                                  = 127.53 Newtons

Thus , the force of a 13kg ball that has been dropped and has fallen for 1 second would be 127.53 Newtons.

Answer:

The distance traveled is 24 meters but the change in position is 0 meters because the person comes back to the same point.

Explanation:

To be straight it is 24 meters.

According to Newtonʼs Second Law of Motion:

F net = m  x  a

or

a = F net / m

Acceleration = net Force/ Mass = 161 / 70 = 2.3 m/s^2  [W]

If a 70 kg skater is acted upon by an unbalanced force of 161 N [West], his acceleration would be 2.30  m/s² towards the west

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

The mathematical expression for Newton's second law is as follows

F = m*a

where F represents the force applied

m is the mass of the object

a is the acceleration of the object

As given in the problem If a 70 kg. skater acted upon by an unbalanced force of 161 N

F =ma

By substituting the values of the force and the mass as 161 N and 70 kg respectively

161 N = 70×a

a= 2.30 m/s²

Thus, If a 70 kg skater is acted upon by an unbalanced force of 161 N, his acceleration would be 2.30  m/s² towards the west

Legend has it that a young Isaac Newton was sitting under an apple tree when he was bonked on the head by a falling piece of fruit, a 17th-century “aha moment” that prompted him to suddenly come up with his law of gravity.

Answer: Gravity has an effect of a gravitational pull, which keeps things on the ground instead of floating around like we are in space.

Answer:

Answer:

5.978 años luz

Explanation:

Hi! Your answer is: The distance between the Barnard's star and Earth is 5.978 light years.

Explanation:

At first it is in 14m position but position doesn't matter in displacement, similar case for time taken.

So at first it travels 6m in positive direction.

So displacement= 6m

Then it travels 13 in opposite or negative direction.

So displacement = 6 -13 m = -7 m

Answer:

41.66 km/h

Explanation:

Calculate the distance of 1st travel :

v = d/t

25 km/h = d/1 h

d = 25 km/h × 1 h

Calculate the distance of 2nd travel :

v = d/t

50 km/h = d/2 h

d = 50 km/h × 2 h

Calculate the velocity of trip :

v = d/t

v = (25 + 100)/(1 + 2)

v = 125 km/3 h

So, my velocity for the trip is 41.66 km/h
