Are the two atoms shown below in the image from the same element?
The answer is yes
They are isotopes.
Not really understanding this, wouldn't mind some help. : )
Explanation:
Given
Mass (m) = 1200 kg
Acceleration (a) = 3 m/s²
Force (F) = ?
We know
F = m * a
= 1200 * 3
= 3600 Newton.
Therefore the force acting on the car is 3600 Newton.

Describe how a magnetic field moves in a magnet. plz help!!
Answer:
In a permanent magnet, the magnetic field comes from the motion of the electrons inside the material, or, more precisely, from something called the electron spin. The electron spin is a bit like the Earth spinning on its axis. The magnetic field is a vector, the same way the electric field is.
Explanation:
Examples of electric forces?
Answer:
Explanation:
The examples of electric force are
The charge in a bulb.
Electric circuits.
Static friction between cloth when rubbed by a dryer.
The shock that is felt after touching a doorknob.

handles on kitchen stove pots are usually made of wood mainly because of ?
A ) Conduction
B ) Convection
C ) Radiation
D ) Condensation
Answer:
(B) Conduction
Explanation:
Answer:
a ) conduction
Explanation:
it's a because if u think about it a conductor keeps the heat from getting to a certain part of the metal

A 13.0km bucket is lowered vertically by a rope in which there is 170N of tension at a given instant. Determine the magnitude of the acceleration of the bucket. Is it up or down?
Answer:
13.07m/s2 down
Explanation:
I think the equation would be
Fnet/m=a
since tension is the only force mensioned that means that
170N/13.0kg=13.07 m/s2 down
acceleration is down

What is the acceleration of a racing car if it's speed is increased uniformly from 44 m /s to 66 m / s over an 11 second period ?
Answer:
the acceleration of the race car is 2 m/s²
Explanation:
Given;
initial velocity of the race car, u = 44 m/s
final velocity of the race car, v = 66 m/s
time of motion of the race car, t = 11 s
The acceleration of the race car is calculated as;
[tex]a = \frac{v-u}{t} \\\\a = \frac{66-44}{11} \\\\a = 2 \ m/s^2[/tex]
Therefore, the acceleration of the race car is 2 m/s²

Answer:I have to say 56
Explanation: because it is going up by 8
Please help me please I need someone to help me with all this question 1) How do we calculate the momentum of a race car? What part of this changes during a collision? 2) What happening to the momentum of the car when they crash? 3) how does impulse factor into this? 4) what type of collision is it ( ideally) when cars crash into this SAFER barrier?
Answer:
Explanation:
1 ) Momentum of a race car = mass of car x velocity of car . During a collision , an external force acts on the car which changes the momentum of the car in the direction in which force acts .
2 )
The momentum of the car decreases as external force acts against the momentum . Sometimes when external force is very high , direction of momentum is reversed .
3 ) Impulse is force x time of action of force . Generally time of action of force in large collision is very small . so it is calculated very carefully .
Impulse = change in momentum .
4 ) The type of collision is inelastic . In this type of collision , car crashes into safer barrier , sticks to it . It does not rebound from the barrier . In case of elastic collision , rebound creates large impulse creating huge damage to the car .

What is hydrogens outer most energy level
Answer:
Students should realize that each atom in a group has the same number of electrons in its outermost energy level. For instance, hydrogen, lithium, sodium, and potassium all have 1 electron on their outer energy level. Let students know that these electrons in the outermost energy level are called valence electrons.
