Answer:

(a) 0.0666 A (B) 0.0666 A

Explanation:

(A) We have given emf E_0=14 V

The resistance of the circuit = 210 ohm

Emf frequency = 100 Hz there is no use of frequency in case of resistive load as it is independent on the frequency

According to ohm's law E_0=iR

So 14=i\times 210

i=\frac{14}{210}=0.0666A

(B) We have given emf E_0=14 V

The resistance of the circuit = 210 ohm

Emf frequency = 100 KHz there is no use of frequency in case of resistive load as it is independent on the frequency

According to ohm's law E_0=iR

So 14=i\times 210

i=\frac{14}{210}=0.0666A

Note : As the resistive load is independent on the frequency so resistance will be same and so current will also be same in both case

A 5.58 kg object with a speed of 35 m/s strikes a steel plate at an angle of 45.0 degrees with the normal to the plate, and rebo
MAVERICK [17]

Answer:

magnitude of vector is 276.19 kg m/s

Explanation:

The initial momentum is vector of magnitude

5.58 \times 35 = 195.3 (kg m/s)  And driven in a coherent manner with initial vector.

same magnitude is momentum after the impact, but it is oriented perpendicularly to initial momentum vector.

So, you have 2 momentum vector of  specified magnitude perpendicular to one another.

 The contrast between such two vectors is a right angle triangle hypotenuse of 195.3 sides

magnitude of vector is  \sqrt{ 195.3^2 + 195.3^2} = 276.19

A sled drops 50 meters in height on a hill. The mass of the rider and sled is 70 kg and the sled is going 10 m/s at the bottom o
navik [9.2K]

Answer:

Efficiency = 10.2 %

Explanation:

Given the following data;

Mass = 70 kg

Height = 50 m

Velocity = 10 m/s

We know that acceleration due to gravity is equal to 9.8 m/s².

To find the efficiency of energy conversion from potential to kinetic;

First of all, we would determine the potential energy;

P.E = mgh

P.E = 70 * 9.8 * 50

P.E = 34300 J

For the kinetic energy;

K.E = ½mv²

K.E = ½ * 70 * 10²

K.E = 35 * 100

K.E = 3500

Therefore, Input energy, I = 34300 J

Output energy, O = 3500 J

Next, we find the efficiency;

Efficiency = O/I * 100

Substituting into the formula, we have;

Efficiency = 3500/34300 * 100

Efficiency = 0.1020 * 100

Efficiency = 10.2 %
