A body is moving with a velocity of 15m/s . If the motion is uniform. How much distance will be the velocity after 10s

Answer:

1) 15.6

2) 2.03

Explanation:

The power output of the electric toaster, P = 2,400 W

The voltage rating of the power outlet, V = 120 V

The number of hours the toaster is used during a month = 6.5 hours

1) Electrical energy, E = Electrical power, P × Time, t

The electrical energy dissipated by the toaster, 'E', is given as follows;

E = 2,400 W × 6.5 hrs = 15,600 Wh = 15.6 kWh

The electrical energy dissipated by the toaster, during the measured month in kWh, E = 15.6

2) Let 'C' represent the monthly cost of toaster and let 'B' represent the amount charged by the local power company, we have;

The charges for (electrical) power by the local power company, B = $0.13/kWh

The monthly cost of the toaster, C = E × B

∴ C = 15.6 kWh × $0.13/kWh = $2.028

By rounding off to 2 decimals, the monthly cost of the toaster (in $), C ≈ 2.03.

Answer:

(a) h = 1.5 m (b) v = 5.29 m/s

Explanation:

1. Given that,

Mass of a rollercoaster cart, m = 4500 kg

It has 67,500 J of gravitational potential  energy.

We know that, the gravitational potential  energy is given by :

[tex]E=mgh[/tex]

Put all the values,

[tex]h=\dfrac{E}{mg}\\\\h=\dfrac{67500}{4500\times 10}\\\\h=1.5\ m[/tex]

2. The kinetic energy of an object is given by :

[tex]E=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2E}{m}}\\\\v=\sqrt{\dfrac{2\times 63000}{4500}}\\\\v=5.29\ m/s[/tex]

Hence, this is the required solution.

Answer:

K.E = 400

Explanation:

Given the following data;

Mass = 0.02kg

Velocity = 200m/s

To find the kinetic energy;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Substituting into the formula, we have;

[tex] K.E = \frac{1}{2}*0.02*200^{2}[/tex]

[tex] K.E = \frac{1}{2}*0.02*40000 [/tex]

[tex] K.E = 0.02*20000 [/tex]

K.E = 400

Answer:

10.1 m/s

Explanation:

Let the coordinates of the pelican's position be (x, y).

Now, since it is dropped from a height of 12.3 m, then initial velocity is zero and using Newton's 2nd law of motion, we have;

12.3 = 0 - ½gt²

½gt² = 12.3

t² = 12.3 × 2/9.8

t² = 2.51

t = √2.51

t = 1.5843 s

Now, it travels 16.0m horizontally before it hits the water below. Using the formula, distance = speed × time, we have;

16 = v_x•t

Thus;

16 = v_x × 1.5843

v_x = 16/1.5843

v_x = 10.1 m/s

Now, the velocity in the vertical y-direction is zero.

Thus;

v = √((v_x)² + (v_y)²)

v = √((10.1² + 0²))

v = 10.1 m/s

check the point where the output device's field wiring is connected to the output rack. ( C )

Explanation:

Given that an indicator light on the output module is indicating that a signal has been sent to the output point where the failed single output device is connected , the best line of action to properly indicate the output device that has filed in the PLC system, is to check the point where the output device's field wiring is connected to the output rack in the PLC system.

A PLC system is a computer control system ( especially Industrial ) that helps in the monitoring the states of input and output devices in an industry.

Answer:

=> Rheostat is an electric device used as a variable resistance, like the regulator of the fan. It is used to change the electric resistance in the electric circuit.

=> Rheostat works on the principle of Ohm’s law. Ohm’s law states that current in a circuit is inversely proportional to the resistance at the given temperature.

Explanation:

Momentum of an object is defined as the product of the mass of object and the velocity with which it is moving.

p = mv

where, p = momentum, m= mass and v= velocity

mass m = 0.7 Kg and v = 20 m/s

p = 0.7×20 = 14 Kg-m/sec

Therefore, momentum of the object  = 14 kg-m

Answer:

W = 30 N

Explanation:

Applying the summation of torques about the wedge for equilibrium, taking the clockwise direction as negative. Since the ruler is balanced horizontally about the wedge. Therefore, the summation of all torques acting about the wedge must be equal to zero.

[tex](70\ N)(40\ cm - 10\ cm)-(30\ N)(50\ cm-40\ cm)-(W)(100\ cm - 40\ cm) = 0\\W(60\ cm) = (70\ N)(30\ cm)-(30\ N)(10\ cm)\\\\W = \frac{1800\ N.cm}{60\ cm}[/tex]

W = 30 N

However, small amounts of these radioactive substances (mostly gases) become mixed with the water that is used to cool the reactor.

Answer:

[tex]L=11.3\ kg-m^2/s[/tex]

Explanation:

Given that,

Angular speed of a skater, [tex]\omega=3\ rot/s=18.84\ rad/s[/tex]

The moment of inertia of the skater, I = 0.6 kg-m²

We need to find the angular momentum of the skater. The formula for the angular momentum of the skater is given by :

[tex]L=I\omega[/tex]

Substitute all the values,

[tex]L=0.6\times 18.84\\\\L=11.3\ kg-m^2/s[/tex]

So, its angular momentum is equal to [tex]11.3\ kg-m^2/s[/tex].

answer :

a) 1780 m^3/sec

b)  23.81 m

Explanation:

a) calculate the number of m^3 of water flowing through an OTEC plant charge

assumption : assuming an ideal heat engine

 Q / t   =  m*c*∆T * (eff) / t

1e^9 J/s = 1g/cc *V(1cal/g°C) * 2°C (6.7%)*(4.184J/cal) / t

Hence:  V / t ( number of m^3 of water ) = 1.78e^9 cc / sec = 1.78 * 10

= 1780 m^3/sec

b) Determine the diameter of pipes

Given that the water flows at  4m/s  ( velocity )

1780 m^3 /sec = A * V  ------ ( 1 )

A = π*d^2/4 =  1780 / 4 = 445 m^2  -------- ( 2 )

v = 4 m/s

Back to equation 2

d^2 = ( 445 * 4 ) / π

      ≈ 567

∴ necessary diameter ( d ) = [tex]\sqrt{567}[/tex] = 23.81 m
