I can't remember how to solve this kind of problem.
So, in desperation, I take a hard look at the units.
I do remember that electric field is measured in volts per meter,
and 1 volt/meter means 1 newton/coulomb. And there it is !
The problem has a quantity of [newtons] and a quantity of [coulombs]
in it. If I divide those, the quotient will be [newton/coulomb], and THAT's
electric field strength !
(3.0 x 10⁻⁹ N) / (1.25 x 10⁻¹⁹ C)
= 2.4 x 10¹⁰ N / C
= 2.4 x 10¹⁰ volts/meter .
Answer:
The incorrect part of the chart is;
Line 1
Chemical 
Reaction Nuclear Reaction
Line 1 Happens in the nucleus of atoms Happens between atoms
Explanation:
The given chart can be presented as follows;
Chemical Reaction Nuclear Reaction
1. Happens in the nucleus of atoms Happens Between atoms
2. Forms new compounds Forms new atoms
3. Involves small amounts of energy Involves large amounts of energy
From the above chart, line 1 is incorrect because a chemical reaction happens between the valence electrons of the reacting atoms while a nuclear reaction is the reaction that takes place between the nucleus of two or more atoms or the nucleus of an atom and a subatomic particle to produce one or more than new nuclide of a new atom with a change in the mass of the nucleus being represented by the large amount of energy in the reaction. Therefore, a nuclear reaction takes place in the nucleus of an atom, forms new atoms and involves large amounts of energy
The correct arrangement is presented as follows;
Chemical Reaction Nuclear Reaction
1. Happens Between atoms Happens in the nucleus of atoms
Answer:
a. Photogates placed at the beginning, end, and at various locations along the track that the car travels on.
b. A meterstick to measure the distance of the track that the car travels on.
Explanation:
Physics can be defined as the field or branch of science that typically deals with nature and properties of matter, motion and energy with respect to space, force and time.
In this scenario, a student is provided with a battery-powered toy car that the manufacturer claims will always operate at a constant speed. The student must design an experiment in order to test the validity of the claim.
Therefore, to test the validity of the claim, the student should use the following measuring tools;
a. Photogates placed at the beginning, end, and at various locations along the track that the car travels on. This device is typically used to measure time with respect to the rate of change of the interruption or block of an infra-red beam.
b. A meterstick to measure the distance of the track that the car travels on.
Hence, with these two devices the student can effectively measure or determine the validity of the claim.
Answer:
Vf = 73.4 m/s
Explanation:
This is the case of vertical motion where we have to find the final velocity of the penny when it hits the ground. We can use 3rd equation of motion to find the final velocity:
2gh = Vf² - Vi²
where,
g = 9.8 m/s²
h = height = 275 m
Vf = Final Velocity = ?
Vi = Initial Velocity = 0 m/s
Therefore,
2(9.8 m/s²)(275 m) = Vf² - (0 m/s)²
Vf = √5390 m²/s²
<u>Vf = 73.4 m/s</u>
Answer:
$ 3085713685.71
Explanation:
= Actual wavelength = 700 nm
= Changed wavelength = 500 nm
Let the wavelength of red color be 700 nm and green be 500 nm
Change in wavelength is
We have the relation
The speed of the vehicle is 85714285.7143 m/s
By how much was the car speeding
The number of 10 km/h in the above speed
Cost of the ticket
The cost of the ticket is $ 3085713685.71
