What is a source of the pressure used to create metamorphic rocks?

The water in the ocean
The air in the atmosphere
The layers of sediment in the ocean
The magma from deep in the ground

Answers

The answer is D, or The magma from deep in the ground.

Explanation:

A wouldn’t make sense because the water in the ocean is only hot if it is the deep end of the ocean. B is incorrect because metamorphic rocks are intrusive, as far as how they form. C is incorrect because the only kind of rock classification with layers is a sedimentary rock. D is correct because as the rock sinks into the mantle, magma heats it up intensely and pressures it.
The magma from deep in the ground. Im pretty sure sorry if I’m wrong.

Your science teacher has provided the following materials to investigate the factors that affect the strength of electric and magnetic forces.

• large iron nail – 5 mm diameter

• 100 cm of thinly wrapped copper wire

• D battery

• electrical tape

• wire strip

• thumb tacks -assorted sizes

• paperclips – assorted sizes

Design an investigation you could carry out to determine the factors that affect the strength of electrical and magnetic forces.

Answers

The strength of the electric field can be estimated as force per electric charge, whereas the strength of a magnetic field depends on the force of electrons and velocity.

Whta is a magnetic field?

A magnetic field can be defined as magnetic work exerted on electric charges that are in motion (movement).

Conversely, an electric field is an area where an electric current is applied and electron force can be estimated per Volts per Meter.

In conclusion, the strength of the electric field can be estimated as force per electric charge, whereas the strength of a magnetic field depends on the force of electrons and velocity.

If the body temperature of a person is recorded as 37°C, what is the person’s body temperature in K? Round your answer to the nearest whole number.

A. 236
B. 3
C. 99
D. 310

Answers

Answer:

D

Explanation:

0 degrees Celsius is equal to 273.15 degrees Kelvin. The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15. in short : T(K) = T(°C) + 273.15

Answer: D

Explanation: 37 celsius is equal to 310.15 kelvin and if you round it to the nearest whole number you get 310.

You serve a volleyball with a mass of 2100 g. The ball leaves your hand with a velocity of 30 m/s. The ball has how much energy? Calculate it.

Answers

Answer:

945 J

Explanation

You have just given the ball kinetic energy, which is given by the following equation:

Ek=0.5xm×v2

So the energy the ball has the moment after you hit it is:

Ek=0.5×2.1×(30)2<— square

Ek=945J
