which measurment describes the amount of heat needed to raise the temperature of one gram of a material by one degree celsius?
ella [17]

<u>Answer:</u>

Specific Heat

<u>Explanation:</u>

Specific heat is the measurement which describes the amount of heat needed to raise the temperature of one gram of a material by one degree Celsius.

It is the amount of heat required per unit mass to raise the temperature by one degree Celsius. The relationship between heat and the temperature change is usually expressed as shown below:

Q=cmΔT

where Q = heat added,

c= specific heat,

m=mass; and

ΔT = change in temperature

Which of the following statements about sunspots is false? a. They are areas of the sun that are "burnt out." c. They are cooler
PSYCHO15rus [73]

Answer: Option (a) is the correct answer.

Explanation:

Sunspots are defined as the dark and cooler areas on the surface of the Earth. A sunspot is present in a region known as photosphere.

Temperature of a sunspot is about 3,800 degrees Kelvin whereas photosphere has a temperature of about 5,800 degree kelvin.

Thus, we can conclude that out of the given options, the statement they are areas of the sun that are "burnt out" is false about sunspots.

If 730-nm and 640-nm light passes through two slits 0.61 mm apart, how far apart are the second-order fringes for these two wave
Naddik [55]

Answer:

X2 - X2'=3.24×10⁻⁴m

Explanation:

Given Data

λ1=730nm=

λ2=640nm

d=0.61 mm

D=1.1 m

Distance of the second bright fringe from the central fringe is given by

Xn = = D x n x2 λ / d

X2 = 2 D λ1 / d

X2' = 2 D λ2 / d

Separation between the second bright fringes of the two wavelengths ( the separation between the second order fringes ) is ,

X2 - X2' = 2 D ( λ1 - λ2 ) / d

X2 - X2'= {2 x 1. 1 (730×10^-9 - 640×10^-9) }/ 0.61 x 10 ^-3

X2 - X2'=3.24×10⁻⁴m

A ball with the mass of 600kg moves at a speed of 8 m/s legatos force is needed to bring it to a stop at 10 s
lorasvet [3.4K]

Answer:

480N

Explanation:

A ball is moving a speed of 8 there fore it had to be add force opposite direction to the ball if it takes to rest. There for ball is subjected to deceleration. First we can find the deceleration

V = U + at

0 = 8 + a×10

a= 0.8 m /s²

Then we can apply newton's 2nd law to determine the force acted by legatos

F= ma

F= 600×0.8

  = 480 N
