A car travels 90m north and 50 m south. What is the total displacement?

Answer:

the process that occurs when liquid changes to gas(boiling) is temperature increases

Answer:

The temperature increases

Explanation:

120m per minute

If you take 960 and divide it by 8 you get 120 then you have the answer 120m per minute

Answer:

Find the dimension of each and every quantity in all the options to check whether they are the same or not. We can use any one formula of each identity to find its dimension.

Complete step by step solution:

To find the dimension of a quantity, we can use any formula related to that quantity but we will use the easiest ones to save time.

Force-

from Newton’s law of motion,

F=maF=ma

Dimension of force =[M][LT−2]=[MLT−2]=[M][LT−2]=[MLT−2]

Work done-

W=F×sW=F×s

Dimension of work=[MLT−2][L]=[ML2T−2]=[MLT−2][L]=[ML2T−2]

Momentum-

p=mvp=mv

Dimension of momentum=[M][LT1]=[MLT−1]=[M][LT1]=[MLT−1]

Impulse-

I=F×tI=F×t

Dimension of impulse=[MLT−2][T]=[

Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to increases which aided in the formation of soil.

The process in which use of solar energy occur by  plants, algae and certain bacteria convert them into chemical energy and starch called as photosynthesis.

Photosynthesis occur in chloroplast of the green plant which has its own DNA, genes and synthesize their own proteins.

photosynthetic Pigments are also involve in this process which is responsible for trapping sunlight present in chlorophyll pigment of chloroplast, like chlorophyll a, b and c.

some of the Bacteria have chlorophyll known as bacteriochlorophyll which can absorb infrared rays, Carotenoids which are yellow, orange or red-coloured pigments that absorb bluish-green light., Xanthophyll, Phycobilins.

Answer:

2,500 Joules (J) or Newton Meter (N M)

Explanation:

Work = Force x Distance

The force in this equation is 500 Newtons. The distance (displacement) is 5 meters. Plug it into the equation above.

Work = 5m x 500n

Work = 2,500 Joules or Newton-Meters.

Therefore 2,500 Joules or Newton Meters of work is done on an object.

Answer:

directly from the source through empty space

Answer:

Equality is the state of being equal in rights word and oportunities

Hi there!

Distance and displacement are different.

Distance is WITHOUT direction (scalar quantity)

Displacement TAKES INTO ACCOUNT direction (vector quantity), and is RELATIVE to the initial point.

DISTANCE:

Add up each segment's position:

0 - 2 sec: 0 m

2 - 5 sec: 10 - 4 = 6 m

5 - 6 sec: 0 m

6 - 8 sec: 10 - 2 = 8 m

8 - 9 sec: 0 m

9 - 12 sec: 5 - 2 = 3 m

Add up:

6 + 8 + 3 = 17 m

DISPLACEMENT:

To find displacement, simply look at the position at the final point (t = 12 sec) and compare to the initial position:

At t = 12: Position = 5 m

At t = 0: Position = 4 m

5 - 4 = 1 m

Doors, Windows & Ventilator is a part of building component which is allow to Air & light move & circulate inward & outward, with in door Human or any other material can be move inside or outside also. here types of doors & windows & ventilation are given with necessity of location, function etc.

Window ventilators are used for ensuring a supply of fresh air from the outside into the interior. They are used in rooms with natural ventilation, mechanical extract ventilation or hybrid ventilation. ... It automatically adjusts the inflow of fresh air depending on the level of relative humidity in the room.

Answer:

The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move. Eventually, most of energy used by organisms is transformed into heat and dissipated.

Answer:

acceleration = 3v 125 m/s^

final speed= 50 m/s

final speed in km/hr = 180 km/hr

Explanation:

A new model BMW can start from rest and travel 400 m in 16 s.then the acceleration during this time would be  1.5625 m/s²

There are three equations of motion given by  Newton

The first equation is given as follows

v = u + at

the second equation is given as follows

S = ut + 1/2×a×t²

the third equation is given as follows

v² - u² = 2×a×s

As given in the problem, A new model BMW can start from rest and travel 400 m in 16 s

distance covered by BMW  = 400meters

initial velocity(u) = 0 m/s

time = 16 seconds

acceleration(a) =? m/s²

By using the second equation of motion given by newton

S = ut + 1/2at²

S = 400 m ,u= 0 m/s , and t =16seconds

400  = 0 + a16²

a =400/256

a = 1.5625 m/s²

For the final speed of the car

v= u + at

v = 0 + 1.5625×16

v = 25 m/s

For calculating the speed in km /h

v = 25 ×3600/1000

 = 90 km/h

Thus, the acceleration during the first 16 s  time would be  1.5625 m/s²

and that is the correct answer

Answer:

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. Thus, swimmers must stroke downward in the water to stay afloat and propel forward. This movement is equal and opposite to the force the water exerts against the swimmer to stop them from moving.

Answer:

1)m=230 kg

 w= 2254( approximately 2300) newtons

g= 9.8 m/s^2(approximately 10)

2)m= 90.5( approximately 88.7) kg

  w= 887 N

  g= 9.8 m/s^2(approximately 10)

3) m= 420 kg

   w= 4,116 (approximately 4220

   g= 9.8 m/s^2(approximately 10)

4) m=15kg

   w=55.5N

   g=3.7 m/s^2
