what temperature change is required to change the length of a 5.5-m steel beam by 0.0012m?

Answers

Answer 1

Answer:

Length of steel = 5.5 m

Increase in length = 0.0012 m

α of steel = 12 x 10-6/K

To find:

Temperature change needed ?

Calculation:

Let the required temperature change be ∆T. (in the photo)

So, temperature change of 18.1 Kelvin is required

What is one way that light waves differ from sound waves?(1 point)

Answers

Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum. The speed of light in a medium is constant.

Two rocks, a and b, are thrown horizontally from the top of a cliff. rock a has an initial speed of 10 meters per second and rock b has an initial speed of 20 meters per second. how would you describe the time it takes for the rocks to reach the ground and the horizontal distance they travel? both rocks hit the ground at the same time and at the same distance from the base of the cliff. both rocks hit the ground at the same time, but rock b lands twice as far as rock a from the base of the cliff. both rocks hit the ground at the same time, but rock a lands twice as far as rock b from the base of the cliff. rock b hits the ground before rock a, and rock b lands twice as far as rock a from the base of the cliff.

Answers

Both rocks hit the ground at the same time and at the same distance from the base of the cliff. Option A is correct.

What is speed ?

Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while u for the final speed. its SI unit is m/sec.

If the  resistance is ignored, things falling near the Earth's surface have the same estimated acceleration due to gravity of 9.8 meters per second.

As a result, the objects' acceleration is the same, and their velocity is growing at a consistent pace.

So that both rocks hit the ground at the same time and at the same distance from the base of the cliff.

Hence, option A is correct.

A Ball A and a Ball B collide elastically. The initial momentum of Ball A is 14.0kgm/s and the initial momentum of Ball B is -9.00kgm/s. Ball A has a mass of 2.00kg and is traveling at -5.00 m/s after the collision. What is the velocity of ball B if it has a mass of 3.00kg

Answers

The total momentum before collision is

14.0 kg•m/s + (-9.00 kg•m/s) = 5.00 kg•m/s

If v is the velocity of ball B after colliding with ball A, the total momentum after collision is

(2.00 kg) (-5.00 m/s) + (3.00 kg) v

Momentum is conserved, so these quantities are equal. Solve for v :

5.00 kg•m/s = (2.00 kg) (-5.0 m/s) + (3.00 kg) v

5.00 kg•m/s = -10.0 kg•m/s + (3.00 kg) v

15.0 kg•m/s = (3.00 kg) v

v = (15.0 kg•m/s) / (3.00 kg) = 5.00 m/s

What is average velocity?

The average velocity is the ratio of the total distance traveled to the total time taken by the body. Its unit is m/sec.

Total distance travelled by the  motorcycle;

Her sister disagrees, so the student supports her argument by asking her sister to observe the brightness of streetlights throughout their neighborhood. Which observation would support the student’s argument?

Answers

Comparing and analyzing the brightness of near and farther streetlight would support the student’s argument.

Which observation would support the student’s argument?

The brightness of nearer streetlight is more as compared to the brightness of the farther light because brightness decreases with the increase in distance.

A 0.400-kg block of iron is heated from 295 oK to 325 oK. How much heat had to transfered to the iron?

Answers

The quantity of heat that was transferred to the block of iron is 5544 J or 5.544 kJ

Quantity of Heat

From the question, we are to determine how much heat was transferred to the block of iron

Using the formula,

Q = mcΔT

Where Q is the quantity of heat

m is the mass

c is the specific heat capacity of the substance

and ΔT is the change in temperature

From the given information,

m = 0.400 kg

ΔT = 325 - 295 = 30 K

Putting the parameters into the equation, we get

Q = 0.400 × 462 × 30

(NOTE: Specific heat capacity of iron = 462 J/kg.K)

∴ Q = 5544 J

Hence, the quantity of heat that was transferred to the block of iron is 5544 J or 5.544 kJ

Answers

Answer:

Mass of Earth (M1) = 6×10^24 kg

Mass of Puppy (M2) = 3.6 kg

Radius (R) = 6371000 m

Universal Gravitational Constant (G) = 6.67 × 10^11

Now,

Gravitational Force = G×M1×M2 / R^2

GF = 6.67 × 10^11 × 6 × 10^24 × 3.6 / (6371000)^2

GF = 144.072 × 10^35 / 40,589,641,000,000
