Answer:
50N increasing
Explanation:
it looks like we want the net force. this is the sum of all forces acting on the object. here the problem is extremely simplified and we are even given the values of force. this looks like the rocket is producing an upward force of 160 newtons. it also looks like maybe weight (gravity) and drag (air resistance) are producing downward force against the rocket. we can say those would be subtracting from the amount of upwards force. so 160-40-70=50N. since the force is positive that means we will still have a magnitude of force vector that points upward and so we will increase.

(3) The potential energy of the F-22 jet fighter is 9.8 × 10⁹ Joules .
What is kinetic energy?Kinetic energy is a type of power that a moving object or particle possesses. When an object undergoes work, which involves the transfer of energy, by exerting a net force, the object accelerates and consequently obtains kinetic energy.
Given:
The velocity of the ball, v = 41 m / s,
The mass of the golf ball, m = 0.045 kg,
(1) Calculate the kinetic energy as shown below,
KE = 1 / 2 × 0.045 × 41²
KE = 37.82 Joules
(2) Calculate the kinetic energy of the F-22 jet fighter as shown below,
KE = 1 / 2 × 600² × 100000
KE = 1.8 × 10¹⁰ Joules
(3) Calculate the potential energy of the jet as shown below,

Answer:
0.0001158443168226212 Celcius (significant digits? who cares.....) or about 0.00021 Fahrenheit
Explanation:
500g=0.5kg
PE=mgh
PE=(0.5)*(9.81)*(1.5)
PE=7.36J
3% of 7.36 is 0.22J is converted to heat

What is centripetal force?
A force that causes a body to follow a curved path is known as a centripetal force. It always moves in a direction that is the opposite of the body's velocity and in the direction of the immediate center of curvature of the path.
It is "a force by which bodies are dragged or driven, or in any manner tend, towards a point as to a center," according to Isaac Newton.
Given parameters:
Mass of the Earth: M = 6.0 × 10²⁴ kg.
Mass of the moon: m = 7.3 × 10²² kg.
Moon's tangential speed: v = 1,025 m/s
Let the distance between the center of Earth and the moon is r.
Hence,
GMm/r² = mv²/r
r = GM/v²
= 6.7 × 10 ⁻¹¹ × 6.0 × 10²⁴ / (1,025)²
= 3.82×10⁸ m.
Hence, by subtracting Earth's radius = 6.4 x 10⁶ m, we get, the distance between Earth and its moon is 3.8×10⁸ m.

Radon-220 is a radioactive gas. It escapes from underground rocks and causes a large part of the natural background radiation in the United Kingdom. It has an atomic number of 86. How many neutrons are there in its nucleus?
Answer: 134 neutrons are there in the nucleus of Radon-220
Explanation:
Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.
Thus, number of protons = atomic number = 86
Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.
Mass number = Number of protons + Number of neutrons
220 = 86 + Number of neutrons
Number of neutrons = 134

Your student desk has been in the room for many hours, it is at thermal equilibrium with the room?
Which part of your desk is colder: the wood or the metal? Why?
Answer:
metal because A: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects. Thermal insulators like plastic and wood don't transfer heat as easily.

A proton moves perpendicularly to a magnetic field that has a magnitude of 4.20 x 10-2 T. What is the speed of the particle if the magnitude of the magnetic force on it is 2.40 x 10-14 N?
Answer:
V=3.57 × 10^6 m/s
hope it is helpful..
The speed of the proton in the magnetic field is 3.57×10⁶ m/s.
To determine the speed of the proton, we need to know about the magnetic force experienced by a charged particle in a magnetic field.
What is the magnetic force on a charge particle in a magnetic field?From lorentz law, the magnetic force on a charge particle is given asF=q×v×B
where, q= charge of the particle
v= speed of the particle
B= magnetic field
What will be the speed of the charge particle, proton, if the magnetic field and force are given?Magnetic force(F)= q×v×Bv=F/(q×B)
Here, B= 4.20×10⁻²TF=2.40×10⁻¹⁴N
q= 1.6×10⁻¹⁹C
Then, v= 2.40×10⁻¹⁴/ ( 4.20×10⁻²× 1.6×10⁻¹⁹)
= 3.57×10⁶ m/s.
Thus, we can conclude that the speed of the proton in the magnetic field is 3.57×10⁶ m/s.

What is the velocity of a 24 kg object with 108 kg m/s of momentum?
A) 3 m/s
B) 4.5 m/s
C) 6 m/s
D) 84 m/s
Answer:
The velocity of the object is 4.5 m/s
Explanation:
Momentum is equal to mass times velocity. We can rearrange that relationship to say that velocity is equal to momentum divided by mass. With that we can say:
v = 108 kg m/s / 24kg
v = (108 / 24) m/s
v = 4.5 m/s

There is a small hole of radius r in a hollow sphere, which is immersed in a liquid. Upto what maximum depth it can be immersed so that liquid may not enter in it? Density of liquid is d and surface tension is T.
Answer:
h = 4T/dgr
Explanation:
Using Laplace law for spherical bubble, the pressure difference P'- P = 4T/r where T = surface tension and r = radius of sphere.
Now, the pressure difference on the hollow sphere P' - P = dgh where d = density of liquid, g = acceleration due to gravity and h = maximum depth to which sphere must be immersed.
So dgh = 4T/r
h = 4T/dgr
