Explanation:

Answer:

the height of the is 6 m.

Explanation:

Given;

potential energy of the object, P.E = 50 J

Height of fall of the object, H = 12 m

Determine the mass of the object, m

P.E = mgh

m = (P.E) / (gh)

m = (50) / (9.8 x 12)

m = 0.425 kg

Let the height of the object at 25 J = h₂

mgh₂ = 25

h₂ = (25) / (mg)

h₂ = (25) / (0.425 x 9.8)

h₂ = 6 m

Therefore, the height of the object at 25 J is 6 m.

Answer:

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. ... The sun provides more energy in an hour than the United States can use in a year!

Answer:

Explanation:

Like most stars, the sun is made up mostly of hydrogen and helium atoms in a plasma state. The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. ... Yet this amount of energy is enormous.

Explanation:

From the question,

The height of the helicopter is given as

h = 3t²......................... Equation 1

After 5 seconds, The height of the helicopter is given as

h = 3(5²)

h = 3×25

h = 75 m.

Note: The small mailbag falls under gravity.

Hence,

h = ut + 1/2(gt²)....................... Equation 2

Where u = initial velocity of the mailbag, t = time, h = height, g = acceleration due to gravity of the mail bag.

Given: h = 75 m, u = 0 m/s ( at the maximum height).

Constant: g = 9.8 m/s²

Substitute these values into equation 2

75 = 0(t) +1/2(9.8t²)

solve for t

1/2(9.8t²) = 75

4.9t² = 75

t² = 75/4.9

t² = 15.31

t = [tex]\sqrt{15.31}[/tex]

t = 3.91 s

Answer:

7 mm per year

Explanation:

It is given that :

The Pacific plate is moving towards north at = 29 mm per year

The Pacific plate is moving towards west at = 20 mm per year

We have to calculate the total relative motion towards the northwest.

So we have to find the resultant of the two motions.

Since the two movements are perpendicular, therefore the angle between the two motions is 90 degree.

Therefore, finding their resultant,

[tex]R^2=(29)^2+(20)^2[/tex]

[tex]R^2=(49)^2[/tex]

R = 7

Therefore, total relative motion towards the northwest is 7 mm per year.

Answer:

126 V

Explanation:

The computation of the rms voltage is shown below:

=  I × R

=(.2) × (10)

= 2 V voltage drop across capacitor

= I × 1 ÷ (?C)

= I ÷ (2 × pi × f × C)

= (.2) ÷ (2 × pi × 10,000 × 10 × 10^-6)

= .318 V voltage drop across inductor

= I × ?L

= I × 2 × pi × f × L

= .2 × 2 × pi × 10,000 × .010

= 126 V

Answer:

2.44 m/s due East

Explanation:

From the question given above, the following data were obtained:

Mass of 1st car (m₁) = 4 Kg

Velocity of 1st car (u₁) = 3 m/s

Mass of 2nd car (m₂) = 5 Kg

Velocity of 2nd car (u₂) = 2 m/s

Final velocity (v) =?

The final velocity can be obtained as follow:

v(m₁ + m₂) = m₁u₁ + m₂u₂

v(4 + 5) = (4×3) + (5×2)

9v = 12 + 10

9v = 22

Divide both side by 9

v = 22/9

v = 2.44 m/s

Thus, the final velocity is 2.44 m/s.

Since both cars was moving due East before collision, and after collision, they stick together, then their direction will be due East.

Explanation:

Answer:

1) as far as I remember

Let's take 20 as vf (final velocity) and 11 as (initial velocity) and 4 as time

So we would use this formula a=vf-vi/t

So 20-11/4

Asnwer 2.25

Oxygen has an atomic number 8, because it has 8 protons and 8 electrons.

The first shell of an atom can hold up to 2 electrons but oxygen has 8 electrons, in that eight electrons 2 are in the first shell, so it has 6 more electrons left. The second shell can hold up to 8 electrons, oxygen has only 6 more electrons after the first shell is full, so it will have 6 electrons in the second shell

From this we know that oxygen has 2 shells so it is in period 2, and by counting from left to right, the sixth box in period 2 lies on group 16

Therefore Oxygen lies on group 16 and period 2

Explanation:

The hot air balloon reaches the highest height turn on the flame for 10 seconds each minute for 2 minutes and cut a large hole in the balloon material to allow excess air out.

Because hot air rises, hot air balloons work. By using the burner to heat the air inside the balloon, it becomes lighter than the cooler air on the outside.

As a result, the balloon floats upwards, as if it were in the water. Obviously, allowing the air to cool causes the balloon to slowly deflate.

Hot air balloons use a flame that can turn on and off to heat air inside a large balloon. The balloon is attached to a basket that can carry people or cargo as it is lifted off the ground and floats in the air.

Turn on the flame for 10 seconds each minute for 2 minutes, and cut a large hole in the balloon material to allow excess air out.

Hence the hot air balloon reaches the highest height turn on the flame for 10 seconds each minute for 2 minutes and cut a large hole in the balloon material to allow excess air out.

Answer:

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

Answer:

a.241.08 m/s b. 196 Hz c. 392 Hz

Explanation:

a. Determine the speed of waves within the wire.

The frequency of oscillation of the wave in the string, f = nv/2L where n = harmonic number, v = speed of wave in string, L = length of string = 1.23 m.

Since f = 588 Hz which is the 6 th harmonic, n = 6. So, making v subject of the formula, we have

v = 2Lf/n

substituting the values of the variables into v. we have

v = 2 × 1.23 m × 588Hz/6

v = 241.08 m/s

b. Determine the frequency at which the wire will vibrate with the first harmonic wave pattern.

The first harmonic is obtained from f when n = 1,

So, f = v/2L = 241.08 m/s ÷ 1.23m = 196 Hz

c. Determine the frequency at which the wire will vibrate with the second harmonic wave pattern.

The second harmonic f' = 2f = 2 × 196 Hz = 392 Hz
