Explanation

X L=V/I=24/1.5=16Ω

L = XL/2πf=16/2π50

= 0.05H

hope this helps you.

Answer:

Hello There!!

Explanation:

I believe the answer is=>5.1 x 10-2H

Here's the explanation:↬

•XL= V/I= 24/1.5= 16Ω

•L= XL/2πf= 16/2π50

So the answer is 0.05H.

The velocity of the watermelon as it hits the ground is 14.715 m/s.

Given the data in the question;

Since the Watermelon was dropped from rest,

Now, we determine the velocity of the watermelon as it hits the ground which is the final velocity.

From the First Equation of Motion:

[tex]v = u + at[/tex]

Now, under gravity, acceleration ''a" will Acceleration due to gravity;[tex]g = 9.81m/s^2[/tex], "v" is the final velocity, "u" is the initial velocity and "t" is the time taken.

So, we substitute our values into the equation

[tex]v = 0m/s\ +\ ( 9.81m/s^2\ * 1.5s )\\\\v = ( 9.81m/s^2\ * 1.5s )\\\\v = 14.715 m/s[/tex]

Therefore, the velocity of the watermelon as it hits the ground is 14.715 m/s

Answer:

b) 72 F°

Explanation:

In Fahrenheit, the difference between freezing and boiling is 180 F° (that’s 212 °F minus 32 °F). In Celsius, the difference is 100 C° (by definition of 0 °C and 100 °C for those two points). So 100 C° = 180 F°; dividing by 100 gives us 1 C° = 1.8 F°.

So a difference of 40 C° is equal to 40 times (1.8 F°) = 72 F°.

Notice I am using °F and °C for actual temperatures, and F° and C° for temperature DIFFERENCES.

Electromagnetic Equipment

An electromagnet is a type of magnet with a magnetic field produced by an electric current. Electromagnets are often used in electrical devices that induce heat for cooking such as an oven (OPTION A).

Capacitor

As the voltage increases, the current decreases (OPTION D).

As the capacitor charges up, the potential difference across its plates begins to increase, and by extension circuit current decreases.

Answer: see below

Explanation:

1) An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Friction opposes relative motion. In its absence, a moving object will not stop.

2) If you stop pushing, the force of kinetic friction will produce an acceleration in the opposite direction of the velocity, and the object will slow down and stop.

3) No they are not the same, as one has friction and the other has no friction.

Mass of copper block m=2kg

Heat released by the copper block is equal to the heat gained by the ice to melt.

Let the mass of the ice melted be M.

Change in temperature of copper block ΔT=500−0=500

∴ mS(ΔT)=ML

f

Or 2×400×500=M×3.5×10

We have that If a 2kg block of copper is heated and a temperature increase of 50C is measured,the energy has been provided is

E=418KJ

From the question we are told

If a 2kg block of copper is heated and a temperature increase of 50C is measured, how much energy has been provided?

Generally the equation for the Energy  is mathematically given as

[tex]E=mC(T_1-T_2)\\\\E=2*4180(50)\\\\E=418000J\\\\E=418KJ[/tex]

Therefore

The kind of stretching they should do before they are warmed up is dynamic stretching.

A dynamic stretch is a movement-based type of stretch. It uses the muscle itself to induce stretching. It differs from traditional "static" stretches because the stretch position is not preserved.

Extend your left foot backward, bend your right foot forward and bend it, and rotate left and right to raise your arms to the sky. Or why not stand and add another kind of gentle twist.

Dynamic stretches are based on movement, while static stretches move the joints as much as possible and hold them for a period of time (usually 30-90 seconds).

Answer:

B. 5Ω

Explanation:

Equivalent resistance between point P and Q

= 3Ω + Tp

Total Parallel resistance, Tp

[tex] \frac{1}{Tp} = \frac{1}{12Ω} + \frac{1}{6Ω} + \frac{1}{4Ω} [/tex]

[tex]\frac{1}{Tp} = \frac{1}{12Ω} + \frac{2}{12Ω} + \frac{3}{12Ω} [/tex]

[tex]\frac{1}{Tp} = \frac{6}{12Ω}[/tex]

[tex]6(Tp) = 12Ω[/tex]

[tex]Tp = \frac{12Ω}{6} [/tex]

[tex]Tp = 2Ω[/tex]

Equivalent resistance between point P and Q

= 3Ω + 2Ω

= 5Ω

Answer: see below

Explanation:

The intial speed is u=0[tex]\frac{m}{s}[/tex]

The acceleration is a= 3.3[tex]\frac{m}{s}^2[/tex]

The distance is s=60m

Apply the equation of motion

[tex]v^{2}[/tex]=[tex]u^{2}[/tex]+2as

So,

[tex]v^{2}[/tex]=0+2*3.3*60=396

v=[tex]\sqrt{396}[/tex] = 19.89 m/s ≈20 m/s

Applying the equation of motion

v=u+at

t= [tex]\frac{v-u}{a}[/tex] =[tex]\frac{19.89-0}{3.3}[/tex] = 6.02seconds
