The direction of force in Coulomb's law is determined by the direction of the electric field created by the charges.
Coulomb's law states that the force between two charged particles is proportional to the product of their charges and inversely proportional to the square of the distance between them. The direction of this force is determined by the direction of the electric field created by the charges.
The electric field is defined as the force per unit charge and can be visualized as the field lines that emanate from a charged particle. The direction of the electric field is always away from a positive charge and towards a negative charge, and the force between two charges will be in the same direction as the electric field at the point where they are located.

which force is greater, the weight of the wrecking ball or the tension in the cable?
Answer: 14.25
Explanation:
tle 14.25
The weight of the wrecking ball and the tension in the cable are equal and opposite forces. When the wrecking ball is hanging vertically, its weight is balanced by the tension in the cable.
The force exerted by the weight of the wrecking ball and the tension in the cable are equal and opposite in direction, but it is difficult to say which is greater without knowing the specifics of the scenario. The tension in the cable will be equal to the weight of the wrecking ball if the cable is in static equilibrium, meaning that the net force on the wrecking ball is zero. In this case, the tension in the cable balances the weight of the wrecking ball, preventing it from falling. If the wrecking ball is in motion, the tension in the cable may be greater or lesser than the weight of the wrecking ball, depending on the motion of the ball and the direction of the tension.

Ahmed is a heating consultant. One of his clients has a boiler that is 62% efficient and uses heating oil that releases 4. 15 x 107 J kg-1 of heat energy when it bums in air. What mass of heating oil does the boiler need to heat 245 kg of water from 12. 0 °C to 68. 0 °C?
Explanation:
To calculate the amount of heating oil needed, we need to first determine the amount of energy required to heat the water. We can use the formula for calculating the energy required to heat a substance:
Q = mcΔT
where
Q is the energy required,
m is the mass of the substance,
c is the specific heat capacity of the substance, and
ΔT is the change in temperature.
For water, the specific heat capacity is 4.18 J/g°C.
Plugging in the values:
Q = 245 kg * 4.18 J/g°C * (68.0°C - 12.0°C) = 45,082,000 J
Next, we need to consider the efficiency of the boiler. The boiler is only 62% efficient, which means that only 62% of the energy released from the heating oil will actually be used to heat the water.
So the actual amount of energy required from the heating oil would be:
Q / 0.62 = 45,082,000 J / 0.62 = 72,619,355 J
Finally, we can use the heat energy released by 1 kg of heating oil to calculate the mass of heating oil required:
72,619,355 J / (4.15 x 107 J/kg) = 17.5 kg
So the boiler would need approximately 17.5 kg of heating oil to heat 245 kg of water from 12.0°C to 68.0°C.

Specify the angle west of north, relative to the earth (i. E. A stationary observer on the shore)
The angle that the vector sum makes with north. The direction the ship must travel is this angle, measured west of north.
We need to determine the angle that the vector sum of the ship's velocity relative to the sea and the ocean current creates with north in order to determine the direction the ship must go in order to have a velocity that is directly north relative to the earth.
Call the angle between the north and the ocean current. The east-west and north-south components of the ship's velocity in relation to the sea may be separated out.
The component along the east-west direction is 5.5 * cos(θ),
and the component along the north-south direction is 5.5 * sin(θ).
Adding the ocean current,
Which has a magnitude of 1.5 and direction 40º north of east, we get:
East component = 5.5 * cos(θ) + 1.5 * cos(40º)
North component = 5.5 * sin(θ) + 1.5 * sin(40º)

The 400nm light travels faster than the 600nm light.Cannot be determined.They both travel at the same velocity,.They both travel at the same velocity, but slower than c
When a light ray propagating in vacuum contains both 600nm light and 400 nm light and is incident on top of a glass cube then 400nm light travels faster than the 600nm light so the answer is (b).
The speed of light in a medium is dependent on the refractive index of the medium, which is a function of the wavelength of the light and the properties of the medium. In general, light with a longer wavelength will travel slower in a medium than light with a shorter wavelength. This is because the longer wavelength light experiences more refraction, or bending, in the medium.
In the case of a glass cube, both the 400 nm and 600 nm light will slow down as they travel through the glass. The 400 nm light will slow down more than the 600 nm light, meaning it will experience more refraction and bend more than the 600 nm light. Therefore, the answer is (b) the 400nm light travels faster than the 600nm light.

suppose that the cost of electrical energy is $0.12 per kilowatt hour and that your electrical bill for 30 days is $60. assume that the power delivered is constant over the entire 30 days. what is the power in watts? if this power is supplied by a voltage of 120 v, what current flows? part of your electrical load is a 60 w light that is on continuously. by what percentage can your energy consumption be reduced by turning this light off?
The power is 694W
What is the most basic meaning of power?
Power can be defined as the amount of work completed in a given amount of time.
The total amount of energy used throughout the course of the 30 days must first be determined.
30 days in a month equal 720 hours.
When the cost per kwh is 0.12 and the total cost is $60 (for 720 hours), we have:
60$/month = 0.12$/Kwh*xKwh/month
Calculating the total energy used during the month
i.e. 60/0.12 will be 500Kwh
Given that power is the rate of change of energy and that the power given is constant throughout the course of 30 days, we may determine the power as follows.
P = E/t
P = 500/720 = 0.694kW = 694W
If the power is supplied by a voltage of 120 V,
I is P/V i.e. 694/120
I = 5.78A
We can deduct the power of a 60-W lamp from the power we just discovered if it makes up a portion of the electrical load.
P = 694 W - 60 W = 634 W
The new value of the energy spent during the entire month will be :
E = 0.634 kW*24(hr/day)*30(days/mo)
E = 456 kWh/mo
The percentage decrease in total energy used can be computed as follows:
ΔE =500-456/500
ΔE = 0.088 *100
ΔE = 8.8%

a player hit a serve in a racket sport that was clocked at 61 mph. how much work did have to do on the -oz ball to get it to that speed?
The work we have to do on the -oz ball to get it to that speed is 62.20 ft.lb.
1 ounce = 0.0625 pound
1 mile per hour is = 1.46667 [tex]\frac{ft}{sec}[/tex]
Now, the speed of ball is =89.46687 [tex]\frac{ft}{sec}[/tex]
Now, to find the weight of the ball=0.0625 ×8
weight of ball=0.5lb
The energy an object has as a result of motion is known as kinetic energy.
A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. After the work is finished, energy is transferred to the item, which then moves at a new, constant speed. Kinetic energy is the type of energy that is transferred and is dependent on the mass and speed attained.
Kinetic Energy=[tex]\frac{1}{2} mv^{2}[/tex]
Kinetic Energy=[tex]\frac{1}{2}\times0.5\times89.46687^{2}[/tex]
Kinetic Energy=2001.082 [tex]\frac{ft^{2} }{sec^{2} }\times lb[/tex]
Now, 1lbf =32.174049[tex]\frac{ft}{sec^{2} }\times lb[/tex]
Now, kinetic energy=[tex]\frac{2001.082}{32.174049}[/tex]
kinetic energy=62.20 ft.lb
Now, kinetic energy will always be equal to work done.
