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.Could someone pls help at #9?

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.

Chemical changes occur as energy is transferred when molecules- - or - to form one or more new substances
Answers
Answer:
Correct options are C. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies.
D. Energy stored in organic fuels are used for heat and electricity/ When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy.
Explanation:
The breakdown of food leads to the release of chemical energy which was first stored in food. This energy is used to drive necessary functions of the body. A series of chemical reactions are involved in the breakdown of food and changing them into useful components for the cell.
Chemical energy is stored in circuits. When the battery is connected to a circuit, the chemical energy gets transferred into electrical energy.

The diagram below shows a wave. The feature of the wave are labeled A, B, C, and D. Which label identifies the wavelength?
Answers
According to the given diagram, the c identifies the wavelength of the curve. Hence, option C is correct.
What is wavelength?In order to characterize waveform signals that are transmitted across wires or into space, the term "wavelength" is used to refer to the separation between two identical positions (adjacent crests) in succeeding cycles. Typically, this length in wireless systems is measured in meters (m), centimeters (cm), or millimeters (mm) (mm). When describing the wavelength of infrared (IR), visible light (UV), and gamma radiation, units of 10-9 nanometers (nm) or angstroms (10-10 m) are more usually used.
The relationship between frequency and wavelength is inverse, with frequency being the number of wave cycles per second. A signal's wavelength shortens as its frequency rises, or we may say that the relationship between wavelength and refractive index is inverse.

Mehanical energy
Please. Mark brainlist
I am not very much sure but I will give a small explanation here
A bow and arrow possesses mechanical energy. When the arrow is drawn it has potential energy and when it is released it produces a force to propel the arrow towards the aimed target, therefore giving the arrow kinetic energy. When you combine both energies it creates mechanical energy

Which of the following is an advantage of circuit breakers over fuses.
A.) It is easier to trip a fuse.
B.) Circuits get hot.
C.) Tripped circuit breakers do not need to be replaced.
D.) Fuses need to be replaced
Answers
One of the advantage of circuit breaker over fuses is tripped circuit breakers do not need to be replaced as fuse does power is in rapid restoration with breakers.
What are circuit breakers?A circuit breaker is an electrical device similar to electrical switches designed to protect the circuit from damges created by over current or short circuit.
Circuit breakers can be operated manually or automatically for saving the electrical network and components. Fuse is another saftey device to provide protection from overcurrent. It is operating automatically and it melts when over current is passed.
Even though fuses can be easily operated and less expensive, power cannot be restored after tripping the fuse whereas, tripped circuit breakers need not be replaced and easily restore the energy as soon.
