A spring (70 N/m ) has an equilibrium length of 1.00 m. The spring is compressed to a length of 0.50 m and a mass of 2.2 kg is p

vodka [1.7K]

Answer:

a) The mass moves a distance of 0.625 m up the slope before coming to rest

b) The distance moved by the mass when it is connected to the spring is 0.6 m

c) $\mu = 0.206$

Explanation:

Spring constant, k = 70 N/m

Compression, x = 0.50 m

Mass placed at the free end, m = 2.2 kg

angle, θ = 41°

Potential Energy stored in the spring, $PE= 0.5 kx^2$

$PE = 0.5 * 70 * 0.5^2\\PE = 8.75 J$

According to the principle of energy conservation

PE = mgh

8.75 = 2.2 * 9.8 * h

h = 0.41

If the mass moves a distance d from the spring

sin 41 = h/d

sin 41 = 0.41/d

d = 0.41/(sin 41)

d = 0.625 m

The mass moves a distance of 0.625 m up the slope before coming to rest

b) If the mass is attached to the spring

According to energy conservation principle:

Initial PE of spring = Final PE of spring + PE of block

$0.5kx_1^2 = 0.5kx_2^2 + mgh\\x_2 = d - x_1 = d - 0.5\\h = d sin 41\\0.5*70*0.5^2 = 0.5*70*(d-0.5)^2 + 2.2*9.8*d*sin41\\8.75 = 35(d^2 - d + 0.25) + 14.15d\\8.75 = 35d^2 - 35d + 8.75 + 14.15d\\35d^2 = 20.85d\\d = 0.6 m$

The distance moved by the mass when it is connected to the spring is 0.6 m

3) The spring potential is converted to increased PE and work within the system.

mgh = Fd + 0.5kx²...........(1)

d = x , h = dsinθ

kinetic friction force , F = μmgcosθ

mgdsinθ + μmg(cosθ)d = 0.5kd²

mgsinθ + μmgcosθ = 0.5kd

sinθ + μcosθ = kd/(2mg)

$\mu = \frac{\frac{kd}{2mg} - sin\theta}{cos\theta} \\\\\mu = \frac{\frac{70*0.5}{2*2.2*9.8} - sin41}{cos41} \\\\\mu = 0.206$

Might a synchronous motor equally well be called a synchronous inductor

sergiy2304 [10]

In Engineering, a synchronous motor is sometimes referred to as synchronous capacitor but not a synchronous inductor.

<h3>What is a synchronous motor?</h3>

A synchronous motor can be defined as an alternating current (AC) electric motor in which the rotation speed of the shaft is directly proportional to the frequency of the supply current, especially at steady state.

Basically, a synchronous motor is sometimes referred to as a synchronous capacitor because it can be used to correct the power factor (PF) of a lagging load such as an induction motor.

However, a synchronous motor cannot be called a synchronous inductor because the rotation speed of the shaft is not proportional to the synchronous speed of the motor. Thus, they are called an synchronous motor.

The direction of rotation of a dc series motor or a universal motor connected to a dc power source A) depends on the polarities

Solnce55 [7]

Answer:

<em>A) depends on the polarities of the armature and field currents.</em>

Explanation:

In the DC series motor, or a universal motor, the field and armature winding are connected in series. This means that if the polarity of the input DC voltage is changed, the direction of the field & armature will also change, resulting in the change of direction of rotation of the motor. This means that the direction of rotation of a DC series motor, or a universal motor connected to a DC power source can be reversed by changing the polarity of the field current, or the armature current.

2.31 LAB: Simple statistics Part 1 Given 4 integers, output their product and their average, using integer arithmetic. Ex: If th

Elden [556K]

Answer:

Explanation:

Note: Integer division discards the fraction. Hence the average of 8, 10, 5, 4 is output as 6, not 6.75.

Note: The test cases include four very large input values whose product results in overflow. You do not need to do anything special, but just observe that the output does not represent the correct product (in fact, four positive numbers yield a negative output; wow).

Submit the above for grading. Your program will fail the last test cases (which is expected), until you complete part 2 below.

Part 2: Also output the product and average, using floating-point arithmetic.

Output each floating-point value with three digits after the decimal point, which can be achieved as follows: System.out.printf("%.3f", yourValue);

Ex: If the input is 8, 10, 5, 4, the output is:

import java.util.Scanner;

public class LabProgram {

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

int num1;

int num2;

int num3;

int num4;

num1 = scnr.nextInt();

num2 = scnr.nextInt();

num3 = scnr.nextInt();

num4 = scnr.nextInt();

double average_arith = (num1+num2+num3+num4)/4.0;

double product_arith = num1*num2*num3*num4;

int result1 = (int) average_arith;

int result2 = (int) product_arith;

System.out.printf("%d %d\n",result2,result1);

System.out.printf("%.3f %.3f\n",product_arith,average_arith);

}

expected output : 1600.000 6.750
