Answer:
F = 30 N
Explanation:
The gravitational force is 2336 N for an object that is 4.15 x 10^6 m above the surface of the Earth? The radius of the Earth is 6.378 x 10^6 m. (Earth's mass is 5.97 x 10^24 kg) What is the mass of the object above earth?
Answer:
34kg
Explanation:
An Abrams tank has a mass of 62,Ō00 kg. If its top speed is 20.0 m/s, what is its momentum at top speed?
Answer:
1240000 kg * m/s
Explanation:
p = momentum
p = mass * velocity in kg* m/s
62,000 kg * 20 m/s = 1240000 kg * m/s

Answer:
1. Heinrich Hertz.
2. James Clerk Maxwell.
3. Thomas Young.
4. Christiaan Huygens.
5. Isaac Newton.
Explanation:
Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
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.

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.

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!

A student on an amusement park ride moves in circular path with a radius of 3.5 m once every 4.5 s. What is the tangential velocity of the student?
Answer:
the tangential velocity of the student is 4.89 m/s.
Explanation:
Given;
the radius of the circular path, r = 3.5 m
duration of the motion, t = 4.5 s
let the student's tangential velocity = v
The tangential velocity of the student is calculated as follows;
[tex]v = \frac{2\pi r}{t} \\\\v = \frac{2 \pi \times 3.5}{4.5} \\\\v = 4.89 \ m/s[/tex]
Therefore, the tangential velocity of the student is 4.89 m/s.

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.

Motors change electrical energy into kinetic energy. The spinning movement of the motor is used to do work, for example, the wheels on a toy car.
Answer:
hope this works
Explanation:
Kinetic energy is defined as the energy of a moving object.
A thrown football, a speeding automobile, a marathon runner, or a rock falling from a cliff, are examples of objects that have kinetic energy.

A force of 20 newtons is used to much a box a distance of 2 meters. How much work was done?
Answer:
40 J
Explanation:
In the case of a rectilinear movement, the work is calculated as the product of Force (N) * movement (m). In your case, unless the angle between the force vector and the displacement vector is different from 0, the work is:
20 N * 2 m = 40 J

How did we see through Venus thick atmosphere?
Answer:
The Venusian atmosphere supports opaque clouds of sulfuric acid, making optical Earth-based and orbital observation of the surface impossible. Information about the topography has been obtained exclusively by radar imaging. Aside from carbon dioxide, the other main component is nitrogen
Explanation:
Because Venus has such a dense atmosphere which is some 100 times thicker than the earth's. Evidently, Venus is sufficiently close to the Sun that the little carbon dioxide it had in its early, Earth-like atmosphere caused the surface to warm up and leach out more carbon dioxide into the atmosphere.
A Normal force of 16N is distributed uniformly on top surface of a cube of edge 6cm. The
pressure on this surface is Rx104Pa. Find the value of R
Answer:
approx. 0.43
Explanation:
Area of the side of the cube is 36 cm or 0.36 m, P= F/A, so R*104=16/0.36, R*104≅44.44, R≅0.43

Answer:
Condensation can also produce water droplets on the outside of soda cans or glasses of cold water. When warm air hits the cold surface, it reaches its dew point and condenses. This leaves droplets of water on the glass or can. When a pocket of air becomes full of water vapor, clouds form.
Explanation:
A girl pushes her little brother on his sled with a force of 200. N for 850. m. How much work is this iſ the fored
of friction acting on the sled is (a) 200. N. (b) 300. N?
Explanation:
Given that,
A girl pushes her little brother on his sled with a force of 200. N for 850. m
We need to find the work done by the force of friction acting on the sled. The force of friction is 200 N
Net force = 200 N - 200 N = 0
Work done = 0
If force of friction is 300 N.
Net force = 300 N - 200 N = 100 N
The work done by a force is given by :
W = Fd
Put values,
W = 100 × 850
W = 85000 J
Hence, this is the required solution.
Water rockets are very different from fuel powered rockets for many reasons. Explain some of the differences between them and why rockets that are launched into space require more power and thrust that water rockets?
Answer:
How is a water rocket different than a compressed air rocket?
Usually the rocket is made from a 2-liter soda pop bottle. Before launch, the bottle is filled with some amount of water, which acts as the "propellant" for the launch. Since water is about 100 times heavier than air, the expelled water produces more thrust than compressed air alone.

A classroom has a volume of 165 m^3. How many moles of gas are in the room if the temperature is 20.0°C and the pressure is 1.00 atm? (Make sure to put P, V, and T in the right units.) (Unit = mol)
The number of mole of the gas present in the room given the data is 0.069 mole
Data obtained from the question Volume (V) = 165 m³Temperature (T) = 20 °C = 20 + 273 = 293 KPressure (P) = 1 atm Gas constant (R) = 8.21 m³.L/Kmol Number of mole (n) =?How to determine the number of mole
The number of mole of the gas present in the room can be obtained by using the ideal gas equation as illustrated below
PV = nRT
