pls give me an answer

Answer:  1231.2 km/h

Explanation: 342 x 3.6 ( because 1 m/s equal 3.6 km/h)

Hey there!

A pulley is a "system" that has a rope attached to carry heavy materials off the ground. Once you pull the rope, the heavy item will be carried.

Hope this helps!

Have a great day!

Answer:

30.5555556 m/s

You can write like "30.56 m/s".

Answer:

Below

Explanation:

You can convert km/h to m/s by dividing the value by 3.6

      110 km/h / 3.6 = 30.5556 m/s

*not sure if your teacher wants you to round to sig figs for this but here it is anyways. Because 110 has 2 sig figs it would be :

    31 m/s

Hope this helps! Best of luck <3

Answer:

16.18 mph

Explanation:

the speed of elevators =

(783×3600)/(33×5280) =

2,818,800/174,240 = 16.18 mph

Zooming I. On the image the red line is just short of the 3rd line past the 7 so it is not 7.3 but just a little under.

Answer: 7.28

Answer:

density is equal to mass divided by volume (m/v)

volume: 12×8×9=864cm³

75÷864=0.09

Answer: 0.09g/cm³

Answer:

54km/hr

Explanation:

Since we have to complete m/s to km/h.

we can simply divide the m/s by (5/18)

so we get 54km/hr

Q:

What characteristic is shared by sunspots, solar flares, and coronal mass ejections? Select the two correct responses.

A:

They tend to occur during active periods of the solar cycle. & They are caused by outward fluctuations of the sun's magnetic field.

Q:Drag each item to the correct location.

A: sunspot: cooler area on suns surface where the magnettic field emerges

solar flare: intense burst of radiation coming from the rapid release of magnetic energy

coronal mass ejection: large bubble of plasma from the rapid release of magnetic energy

Q: Which is the cause of the sun's magnetic properties?

A: uneven churning of plasma

Explanation:

took quick check

good luck yall

The uneven churning of plasma is the cause of the sun's magnetic properties, therefore the correct answer is option B.

A magnetic field could be understood as an area around a magnet, magnetic material, or an electric charge in which magnetic force is exerted.

For a simple bar magnet, N-pole and S-pole are the points on a magnet that have the strongest magnetic field. The magnetic field originates from the north pole and terminates in the south pole of a magnet.

The positively charged ions and negatively charged electrons that make up the plasma of the Sun move around a lot due to its high temperatures. Multiple intricate magnetic fields that twist and turn are produced by the moving plasma. A magnetic field is produced by the extremely hot plasma that escapes from the Sun as the solar wind.

Thus, The sun's magnetic properties are caused by uneven plasma churning, so option B is the correct answer.

SI unit:-

SI unit of density is kg/m^3

CGS unit of density is g/cm^3

Hi,

The man on the ground in standing position has more pressure. This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.

To the point, a man standing position on the ground had more pressure.

More is the area of contact, less is the pressure efforted.

Thank you...

Answer:

It took 2 hours

Explanation:

[tex]{ \bf{time = \frac{distance}{speed} }} \\ [/tex]

distance is 90 miles

speed is 45 miles per hour

[tex]t = \frac{90}{45} \\ \\ t = 2 \: h[/tex]

Answer:

2 hours

Explanation:

45 times 2 is 90

Answer:

25,000 joules

given the formula

Q=Mc(final temperature - initial temperature)

M=50 grams convert to kilogram 0.5

c= 4200 j/kg/k

final temperature=32c

initial temperature=20c

Answer:

all of these very easy questions

Answer:

your answer is (B) decreasing

I hope it's helps you

the pressure is (200 N)/(10 cm2)×(100 cm/M)2=200,000 pa

Answer:

element name = neon

no of proton = 10

no. if neutron = 9

atomic no. = 10

atomic weight = 20.17179u

it lies in group 18 and period 2

it is nonmetal because it is a noble gas .

hope this helped you ☺️

Answer:

Vision Correction

You probably know people who need eyeglasses or contact lenses to see clearly. Maybe you need them yourself. Lenses are used to correct vision problems. Two of the most common vision problems are myopia and hyperopia.

Explanation:

hope this helps

Answer:

F = M a    Newton's second law

F = - K x     force exerted by compressed spring

a = - K x / M

a) is true because the ball originally is accelerated due to gravity and this acceleration will decrease as the spring in compressed

One could argue for (d) if the downward direction was designated as negative

Prior to maximum compression of the spring the velocity would negative and as the spring began to extend (and the ball began move upward) the velocity of the ball would change from negative to positive

It would be 0.01023.

0.010229 has 5 sig. fig.'s (leading zeros do not count)

So rounding to 4 sig. fig.'s is just a matter of rounding off the last digit, which leaves you with 0.01023.
