How do we know when an object is in static or dynamic equilibrium?
Answers
Answer:
First Condition of Equilibrium
Explanation:
This means that both the net force and the net torque on the object must be zero. The condition Fnet=0 F net = 0 must be true for both static equilibrium, where the object's velocity is zero, and dynamic equilibrium, where the object is moving at a constant velocity.The sum of the forces on it in each direction is zero. The sum of the torques on it in each direction is zero. Its linear momentum is zero.In music, the note G above middle C has a frequency of about 392 hertz.

Bill and Nageen have each built an electric motor and they are testing them by having them lift boxes. Bill's motor lifts a box 0.39 metres in 2 seconds. Nageen's motor lifts the same box 0.35 metres in 2 seconds. Whose motor has applied more power to the box?
Answers
Answer:
Bill's motor
Explanation:
Bill's motor lifts a box 0.39 metres in 2 seconds.
Nageen's motor lifts the same box 0.35 metres in 2 seconds.
Power = Work done/time
or
[tex]P=\dfrac{mg\times h}{t}[/tex]
Power of bill's motor,
[tex]P_1=\dfrac{m\times 9.8\times 0.39}{2}\\\\P_1=1.91m\ Watts[/tex]
Power of Nageen's motor,
[tex]P_2=\dfrac{m\times 9.8\times 0.35}{2}\\\\P_2=1.71m\ Watts[/tex]
So, Bill's motor applied more power to the box.

Sally's mass on Earth is 50 kg. What is her mass on the moon?
Answers
Answer:
Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object's mass by this quanitity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.
Explanation:
does this help
Sally's mass on Moon is: C. 50 kg
Mass is a measure of the amount of matter that an object or a body is typically made up of. The standard unit of measurement for the mass of an object is kilograms (kg).
Regardless of the location of a person, an object at any given time, mass (amount of matter that they're made up of) is always the same i.e constant.
This ultimately implies that, whether you're on the Moon, space, planet Earth or any other place; your mass would always remain the same or constant.
In this scenario, Sally's mass on Earth is 50 kg. Thus, we can deduce that her mass on Moon would be 50 kg.

Answers
Answer:
49,000 Pa
49 kPa
Explanation:
P (pressure)= hρg, where h= height, ρ=density, and g= acceleration due to gravity.
50 m * 1000kg/m³ * 9.8 m/s²
=49,000 kg*m⁻¹s⁻² OR 49,000 Pa OR 49 kPa

Answer:
1.308104*10^-8 N (1.31*10^-8 N when rounded)
Explanation:
The mathematical formula for gravitational force is F = G Mm /r^2 where G is the gravitational constant which is measured 6.674 *10^ − 11 N (m/kg) ^2.
Since both objects, M and m, have masses of 70kg and the distance r is 5 meters, then we can plug these values into the formula:
F=GMm/r^2
F=(6.674*10^-11)(70)(70)/(5^2)
F=(6.674*10^-11)(4900)/25
F=(3.27026*10^-7)/25
F=1.308104*10^-8
So the gravitational force of attraction between the two objects is 1.308104*10^-8 N.
State the Law of Electric Charges in your own words.
Answers
[tex] \\ [/tex]
According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.
Things that are negatively charged and things that are positively charged pull on (attract) each other. This makes electrons and protons stick together to form atoms. Things that have the same charge push each other away (they repel each other). This is called the Law of Charges.

Answer:
mass
Explanation:
The mass of water in the kettle is 0.50 kg. The specific heat capacity of water is 4200 J/kg °C. The initial temperature of the water is 100 °C. Calculate the average power output from the water in the kettle to the surroundings in 2 hours
Answers
Answer:
1.27 Mega watt approx
Explanation:
Given data
Mass= 0.5kg
c= 4200 J/kg °C
T1= 100°C
Time = 2 hours >>>> 7200 seconds
From the given data the water is already at the boiling point
Hence if continuous heat is being added the latent heat of vapourization will result, the latent heat of vaporization is about 2,260 kJ/kg
Q= mL
Q= 0.5*2,260
Q = 1130kJ
Power= Energy * Time
Power= 1130* 1130
Power= 1.27mega watt approx
