Answer:
800N is the answer
Explanation:
hope it helps
The force between the objects is 200 N and when the distance between the objects is halved then the force between them will be equal to 800 N.
What is Force?A force in physics is an input that has the power to change an object's motion. A mass-containing object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can also be used to describe forces.
Being such a vector quantity, a force does have magnitude and direction. The SI unit metric newton is used to measure it (N). The letter F stands for force.
According to Newton's second law's original formulation, an object's net force is equal to the speed that its momentum is changing over time.
As per the given information in the question,
Force, F = 200 N
F1 = G × m₁m₂/ r²
The final force F' = G × m₁m₂/ (r/2)²
= 4G × m₁m₂/ r²
= 4F
So, when the distance between objects is halved, then the force between them increases to 4 times.
So, the force will be,
4F = 4 × 200
= 800 N.

Answer:
v_t = [tex]\frac{2 g \ ( \rho_b - \rho_l ) r^2 }{9 \ \eta }[/tex]
Explanation:
Let's describe the motion and forces on the marble when it falls into the graduated cylinder filled with water.
Initially, the marble in the air falls under the influence of its weight (gravity force), when it enters the water, a friction force appears that INCREASES with SPEED and opposes the movement, this force is called Stokes force.
Fr = 6π R η v
where η is the viscosity of water
also because of this in a liquid it has an upward thrust, given by Archimedes' law, this thrust is CONSTANT
B = ρ_l g V_l
in that case the volume of liquid(V_l) is equal to the volume of the marble.
Constant force of gravity
W = mg
using the concept of density
ρ_body = m / V
W = ρ_body g V_body
we apply Newton's second law
Fr + B - W = ma
the friction force increases and the other two are constant, so acceleration decreases until reaching zero, at this point the forces are in BALANCE
Fr + B - W = 0
and the speed remains constant, being called TERMINAL SPEED
v_t = [tex]\frac{2 g \ ( \rho_b - \rho_l ) r^2 }{9 \ \eta }[/tex]
from this point on, the displacement is proportional to the time

However, the various definitions of light according to early scientists include the following;
1. Heinrich Hertz: Light is a wave that has similar properties as radio waves. Heinrich Rudolf Hertz was a German physicist born on the 22nd of February, 1857 in Hamburg, Germany. The unit of frequency ("Hertz") of an electromagnetic wave was named after him.
2. James Clerk Maxwell: Light is a wave made of electric and magnetic fields. James Clerk Maxwell was a Scottish physicist born on the 13th of June, 1831 in Edinburgh, United Kingdom. He was famously known for his work in the formulation of the classical theory of electromagnetic radiation.

It is the angle the incident ray makes with a line drawn perpendicular to the reflecting surface.
It is the angle the incident ray makes with a line drawn parallel to the reflecting surface.
the angle of incidence is always equal to the angle of reflection,
Explanation:
Important Information. When light is reflected from a surface, the angle of incidence is always equal to the angle of reflection, where both angles are measured from the path of the light to the normal to the surface at the point at which light strikes the surface. This equality is known as the law of reflection.
Answer:
It is the angle the incident ray makes with a line drawn perpendicular to the reflecting surface

How do the nuclei of covalently bonded atoms help keep the bond together?
Neutral particles in the nucleus provide enough mass that the force of gravity holds the atoms together.
Neutral particles in the nucleus can become positive or negative in order to balance the charges.
Positive particles in the nucleus change into negative particles that enter electron shells.
Positive particles in the nucleus are attracted to shared electrons, so the atoms stay close together.

Two trucks have the same mass. Which truck will have a greater amount of kinetic energy? b. The truck with less mass d. The trucks will have the same kinetic energy c. The truck with greater speed a. The truck with more mass
Answer:
c. The truck with greater speed
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents speed or velocity measured in metres per seconds square.
From the above formula, we can deduce that the kinetic energy of an object is directly proportional to the square of the value of its velocity or speed.
Hence, the truck with greater speed would have a greater amount of kinetic energy.
Answer:
The trucks will have the same kinetic energy.
Explanation:
Both of the trucks have the same mass, so they have the same kinetic energy. Hope this helps!

How does a recessive allele “show up” to be seen?
Answer:
Recessive alleles only show their effect if the individual has two copies of the allele.
Explanation:
Dominant and Recessive Alleles If your allele pair is FF or Ff, you will have freckles. The only way you can escape a freckled face is to inherit the recessive gene from each parent, giving you the ff allele pair. In general, recessive alleles show up in your phenotype only if you have two of them.
Three dogs scout sparky and dusty are playing with a teddy bear. Scout and sparky are pullung the teddy bear to the left
Answer:
To the left side.
Explanation:
The teddy bear will move towards the left side because more force is applied by scout and sparky than dusty. The reason for this movement of teddy bear to the left is due to more force is applied by the two dogs present at the left side of the teddy bear while on the other hand, one dog is present at the right side of teddy bear which applied less force so that's why we can say that the teddy bear moves to the left side rather than to the right side.

A. The speed of the object will decrease.
B. The speed of the object will increase.
C. The speed of the object will remain the same.
D. The direction of the object's velocity will change.
Answer:
C
Explanation:
Grammar is probably one of the most important components of the sciences besides math.
no unbalanced forces means that there is no force left over that cause an acceleration. All the forces are balanced.
So the Speed will not decrease. Not A.
The speed will not increase. Not B
The direction will not be affected. Not D
The answer is C
