Answer:

Explanation:

A magnet has a magnetic field around it which originates at the north pole and enters through the south pole.

In a magnet, like poles will repel each other and unlike poles will attract.

The north pole of one magnet will repel another north pole of another magnet.
North pole of one magnet will attract the south pole of another magnet.
This is the law of attraction and repulsion of magnet.

Help plz I don't understand

Airplane start with initial speed

$v_i = 0$

now the takeoff velocity is given as

$v_f = 300 km/h$

$v_f = 83.33 m/s$

acceelration is given as

$a = 1 m/s^2$

now we have

$v_f - v_i = at$

from above equation we have

$83.33 - 0 = 1(t)$

$t = 83.33 s$

Airplane start with initial speed

$v_i = 0$

now the takeoff velocity is given as

$v_f = 300 km/h$

$v_f = 83.33 m/s$

acceelration is given as

$a = 2 m/s^2$

now we have

$v_f - v_i = at$

from above equation we have

$83.33 - 0 = 2(t)$

$t = 41.7 s$

When a runner increases her speed from 75 m/s to 115 m/s in 25 s,her acceleration is _____

Angelina_Jolie [31]

The acceleration would actually be 1.6 m/s^2. Acceleration= final velocity-initial velocity/time taken. When you do that formula it comes out to equal that.

A person of mass m measures their weight with a scale. How does the person’s weight measurement at the equator, WEQ, compare wit

lakkis [162]

Answer:

Weight measurement at poles will be slightly more than at equator.

Explanation:

Firstly earth bulges at equator. This makes the body far from earth center at equator than poles. Secondly, the surface centrifugal forces of earth due to rotation also plays vital role in disturbing the gravity value. The centrifugal forces cancel the effect of gravity more at equator than at poles.These factors combine to create difference of about 0.5% in gravity values at pole and equator.

gravity at pole=9.832 m/s^2

gravity at equator=9.780 m/s^2

the speed of a tortoise and a hare are 1m/s and 3m/s. the mass of hare is 5kg and the tortoise is 20kg. which has greater moment

Novosadov [1.4K]

Answer: tortoise

Explanation:

Given the following :

Speed of tortoise = 1m/s

Speed of hare = 3m/s

Mass of hare = 5kg

Mass of tortoise = 20kg

Momentum = product of Mass and velocity

Momentum of hare = mass of hare × Velocity of hare

Momentum of hare = 5kg × 3m/s = 15kgm/s

Momentum of tortoise = mass of tortoise × Velocity of tortoise

Momentum of tortoise = 20kg × 1m/s = 20kgm/s

Therefore, tortoise has a greater momentum than hare.
