Answer:
1) Buoyant force, 2) sinks, 3) equilibrium, 4) fleet , 5) LIFT force
Explanation:
A body in a fluid is subjected to two forces, its weight and the thrust
sun F = B - W
the em
bid is always vertical and contrary to weight, let's analyze and complete the different situations presented
1) Buoyant force
2) sinks B <W
3) equilibrium B = W
4) fleet B> W
5) by the sum of two forces:
* Thrust, but the density of air is much less than the density of water, therefore the thrust in the air is less.
* The other force in airplanes the lift force given by the difference in the path of the air when the plane moves, which translates into a pressure difference between the upper part of the wing and the lower part, it is force is called LIFT force

A force of 200N acts between two objects at a certain distance apart .the value of the force when the distance is halved is?
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.

on which factor does gravitation between any two bodies depend?
Answer:
Gravitational force between two bodies depends on:
1. Masses of the two bodies. The greater an object's mass, the greater its gravitational force.
2. Distance of separation between them. The smaller the distance greater is the gravitational force.

A toy car has a motor capable of moving the car at 10m/s up a 35 degree ramp. If the motor exerts a force of 500N to the car, what is the power rating of the motor in kW?
Answer:
4.096 kW
Explanation:
Applying,
P = Fvcos∅................. Equation 1
Where P = Power of the motor, F = Force exerted on the motor, v = Velocity, ∅ = angle.
From the question,
Given: F = 500 N, v = 10 m/s, ∅ = 35°
Substitute these values into equation 1
P = 500×10×cos35°
P = 4095.8 W
P = 4.096 kW
Hence the power rating of the moto in kW is 4.096 kW

Answer:
apples falling from trees people's feet touching the ground sky divers moving toward the ground balls bending downward after being thrownExplanation:
When a space ship is accelerating in space, there is a force known as Inertia that kicks in. Inertia will mirror the effects of gravity on the ship even if there is no gravitational field effect such that anything that would happen where there is gravity, would continue to happen.
This means that apples will fall from trees, people's feet will touch the ground, sky divers will be pulled downwards and balls will bend downwards when thrown as well. These are the same effects expected on earth where gravity pulls things towards the earth's core.

The Grand Canyon is more than 400 km long and in some places almost 2 km deep. Which model best represents the main process that formed the Grand Canyon?
Answer: Diagram A
Explanation:
The Grand Canyon was created by the constant flow of the Colorado river which physically broke down the rock for billions of years. It then carried off the rock as it flowed and as it kept doing this, the canyon kept getting deeper and deeper.
This is what is described in the first diagram. The water from the faucet is carrying the soil along with it much like the Colorado did to the rocks of the Grand Canyon.
A dog is running in a circle around a tree, trying to catch a rabbit. The dog's owner notices the
dog completes 4 laps around the tree in 32 seconds and the radius of the dog's circular path is
3 meters. What is the tangential velocity of the dog?
Answer: 2.35 m/s
Explanation:
Given
Dog completes 4 laps around the tree in 32 seconds
Radius of the circular path is 3 m
Time period for single lap is [tex]\frac{32}{4}=8\ s[/tex]
Length of the track is equivalent to the perimeter of the path
[tex]\Rightarrow L=2\pi r\\\Rightarrow L=2\pi \times 3\\\Rightarrow L=6\pi\ m[/tex]
Tangential velocity is given by
[tex]\Rightarrow v_t=\dfrac{L}{t}\\\\\Rightarrow v_t=\dfrac{6\pi}{8}\\\\\Rightarrow v_t=2.35\ m/s[/tex]
Thus, the tangential velocity is 2.35 m/s

When a certain metal is illuminated with light of frequency 2.9 ✕ 1015 Hz, a stopping potential of 7.0 V is required to stop the most energetic ejected electrons. What is the work function of this metal?
Answer:
4.96 eV
Explanation:
Recall the Einstein photoeletric equation;
KE = E - Wo
Where;
KE = kinetic energy of the ejected photoelectron
E= energy of the incident photon
Wo = Work function
But
KE = eV= 1.6 * 10^-19 C * 7 V /1.6 * 10^-19 C = 7 eV
E = hf/e = 6.6 * 10^-34 * 2.9 ✕ 10^15 Hz/1.6 * 10^-19
E = 11.96 eV
Hence;
Wo = E - KE
Wo = 11.96 eV - 7eV
Wo = 4.96 eV
Two point charges of +20.0 μC and -8.00 μC are separated by a distance of 20.0 cm. What is the intensity of electric field E midway between these two charges?
Answer:
The intensity of the net electric field will:
[tex]E_{net}=E_{1}+E_{2}=2.52*10^{7}\: N/C[/tex]
Explanation:
Here we need first find the electric field due to the first charge at the midway point.
The electric field equation is given by:
[tex]|E_{1}|=k\frac{q_{1}}{d^{2}}[/tex]
Where:
k is Coulomb's constantq(1) is 20.00 μC or 20*10⁻⁶ Cd is the distance from q1 to the midpoint (d=10.0 cm)So, we will have:
[tex]|E_{1}|=(9*10^{9})\frac{20*10^{-6}}{0.1^{2}}[/tex]
[tex]|E_{1}|=1.8*10^{7}\: N/C[/tex]
The direction of E1 is to the right of the midpoint.
Now, the second electric field is:
[tex]|E_{2}|=k\frac{q_{2}}{d^{2}}[/tex]
[tex]|E_{2}|=(9*10^{9})\frac{8*10^{-6}}{0.1^{2}}[/tex]
[tex]|E_{2}|=7.2*10^{6}\: N/C[/tex]
The direction of E2 is to the right of the midpoint because the second charge is negative.
Finally, the intensity of the net electric field will:
[tex]E_{net}=E_{1}+E_{2}=2.52*10^{7}\: N/C[/tex]
I hope it helps you!
The net electric field midway between these two charges is 2.52 x 10⁷ N/C.
Electric field strengthThe electric field strength between two point charges is the force per unit charge.
Electric field strength due to +20.0 μC charge
[tex]E _1 = \frac{kq_1}{r^2} \\\\E_ 1 = \frac{9 \times 10^9 \times 20 \times 10^{-6}}{(0.1)^2} \\\\E _1 = 18 \times 10^6 \ N/C[/tex]
Electric field strength due to -8μC charge
[tex]E _2 = \frac{kq_2}{r^2} \\\\E_ 2 = \frac{9 \times 10^9 \times 8 \times 10^{-6}}{(0.1)^2} \\\\E _2 = 7.2 \times 10^6 \ N/C[/tex]
The net electric field midway between these two charges is calculated as follows;
[tex]E_{net} = 18 \times 10^6 \ + \ 7.2 \times 10^6\\\\E_{net} = 25.2 \times 10^6 \ N/C\\\\E_{net} = 2.52 \times 10^7 \ N/C[/tex]

Iqbal has push a lighter box and seema has to push a similar heavier box on the same floor . Who will have to apply a larger force and why ?
Answer: Seema
Explanation:
When an object is on the floor, there is a force of friction acting on it. This force is higher if the object is heavier because the object would be pushing against the floor with more force.
To push such an object, one would have to apply enough force to break the friction holding the object to the floor and so with heavier objects, more force is needed to push the object because there is more friction acting on it.

Brad is swimming in the ocean on a hot sunny day. He finds the water to be much colder than the sand on the beach, even though the sun is warning them both. Identify the reasons for brads observation
Answer:
When Brad was swimming in the ocean and then he observed that the sand was more hotter than the water of the ocean. The water is colder than the sand because the water needs more energy as compared to sand to change its temperature. This is because the water has a higher specific heat than sand.
