Why is the Greenland ice sheet so important to understanding earths past climate?

Answers

Answer:

The ice sheet as a record of past climates

Scientists have, using those ice cores, obtained information on (proxies for) temperature, ocean volume, precipitation, chemistry and gas composition of the lower atmosphere, volcanic eruptions, solar variability, sea-surface productivity, desert extent and forest fires.

Answer:

The Greenland ice sheet is the last remaining ice sheet from the most recent ice age. Therefore, it can tell scientists about the climate conditions of that period.

The current in the wires of a circuit is 60.0 milliAmps. If the
voltage impressed across the ends of the circuit were
doubled and the resistance were tripled, then its new current
would be ___ milliAmps.

Answers

Answer:

I' = 40 mA

Explanation:

Given that,

The current in the wires of a circuit is 60.0 mA.

If the  voltage impressed across the ends of the circuit were  doubled and the resistance were tripled such that,

V' = 2V and R'=3R

The relation between current, voltage and resistance is given by :

V = IR

Let I' be the new current. So,

V'=I'R'

⇒ [tex]I'=\dfrac{V'}{R'}\\\\I'=\dfrac{2V}{3R}\\\\I'=\dfrac{2}{3}\times \dfrac{V}{R}\\\\I'=\dfrac{2}{3}\times I\\\\I'=\dfrac{2}{3}\times 60\\\\I'=40\ mA[/tex]

So, the new current would be 40 mA.

Answer:

No. If you apply a force in a chair, for example, you only will be able to move the chair if you beat the static frictional force. So, with that example, we can see that is not any type of force that can produce movement. The only force that produces movement is a result force which is non-zero.

Answers

Answer:  Hand span

Explanation: Hand span is not a standard unit.

Second is the unit of time.

Meter is the unit of length or distance covered by an object.

Gram is the unit of weight of an object.

Hand span is not a standard unit. This is because the size of hand varies from person to person. Hence, the correct option is (c) "hand span".

Hand span is not a standard unit

One day, Pinki was ironing the clothes in her room. After half an hour of ironing, the light went off and Pinki went outside to the lobby of her house to check it there was any problem in the household circuit. At the same time, she listened the voice of her 4 years old daughter from the same room where she was ironing the clothes. Her daughter was about to touch the hot electric iron but at the same moment, Pinki entered in the room and pushed her daughter back from that place.

(a) On which effect of electric current, does the electric iron works?

(b)State the effect of electric current described here.

(c) Mention the values showed by Pinki here.
PLEASE ANSWER ASAP

Answers

Answer:

(a) An electric iron works on the heating effect of electric current

(b) The heating effect of an electric current is the tendency for electric current to cause the temperature of the material through which it is flowing to rise due to the resistance of the material

The heating effect, 'E', is given by the formula, E = I²·R·t

Where;

I = The current flowing

R = The resistance of the material

t = The time the material takes to heat up

(c) The values showed by Pinki here is the value of care, concern and prevention, to prevent the harmful effect of the high heat on the skin of her daughter

How fast is a skydiver going after 5 seconds or free fall and how far did he fall

Answers

Answer:

It's typically around 120mph. You'll reach this speed a few seconds into your jump, so for those few moments straight out the door, you'll be falling a bit more slowly and therefore covering less distance. We usually estimate around 10 seconds for the first 1,000 feet, then 5 seconds for each 1,000 feet after that.

C. Geothermal energy is not always found in an area that is easily accessible.
D. Geothermal energy can only be used to grow tropical fruits.

Answers

Geothermal energy is not always found in an area that is easily accessible. (C)

Geothermal energy is not a possible energy source for many regions of the country. Because geothermal energy is not always found in an area that is easily accessible. Option C is correct.

What is geothermal energy?

Geothermal energy is the thermal energy in the Earth's crust that comes from the planet's creation and the radioactive decay of components in nearly equal amounts.

The disadvantage of using the geothermal energy is;

A. It is available only in limited areas.

B. It can cause air and groundwater pollution.

C. It is difficult to transport from place to place.

Geothermal energy is not a possible energy source for many regions of the country . Because geothermal energy is not always found in an area that is easily accessible.

When drawing a vector, you should represent the magnitude of the vector by the length of the arrow. A. True O B. False​

Answers

Answer: A. True

Explanation:

Answer:

A. True

Explanation:

A vector in this sense is a thing that has both magnitude (length) and direction.

Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.

This doesn't give any information about where you started or any information about where you ended up after those 2 hours.

This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.

Velocity is a vector.

A weightlifter lifts a set of weights a vertical distance of 2.0 m. If a constant net force of 350 N is exerted on the weights, what is the net work done on the weights?

Answers

Answer:

700 Joules

Explanation:

The work done equals force times distance. Just multiply your two values there.

Side note: It would be more impressive if he'd done it in 1 second rather than 5. You know why? Because POWER=WORK/TIME. The less time it takes him to lift the weight with the same force and distance, the more powerful he is!

What is the mass of a large ship that has a momentum of 1.60x10^9 kg*m/s and is moving at a velocity of 10m/s?

Explanation:

p=mv

p=1.6x10^9

v=10m/s

rearrange and substitute:

m=(1.6x10^9)/10

m= 1.6x10^8 kg.

A drone flies upward with a velocity of 5m/s and has a kinetic energy of 90J What is the mass of the drone?
O 5.4 kg
1.9 kg
7.2 kg
3.6 kg

Answers

Answer:

m = 7.2 kg

Explanation:

Given that,

The velocity of the drone, v = 5 m/s

The kinetic energy of the drone, E = 90 J

We need to find the mass of the drone. The formula for the kinetic energy of an object is given by :

[tex]K=\dfrac{1}{2}mv^2\\\\m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 90}{(5)^2}\\\\m=7.2\ kg[/tex]

So, the mass of the drone is 7.2 kg.
