Answer:

C = frequency × wavelength, where C is the speed of the photons which is the speed of light ~3×10^8

frequency = C/wavelength

f = 3×10^8/400×10^-9m

f = 3/4 × 10^15Hz

f = 0.75×10^15Hz

f = 7.5×10^14Hz

Answer:

A) 75m

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

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

The motorcycle's average velocity will be 6 m/sec. The ratio of the overall distance traveled to the total time taken by the body is the 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;

d=20 m+10 m

d=30 m

The average velocity is found as;

[tex]\rm v_{avg}=\frac{d}{t} \\\\ \rm v_{avg}=\frac{30}{5} \\\\ v_{avg}= 6 \ m /sec[/tex]

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

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

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.

Answer:

D) 12.3

Explanation:

took the test

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
