From the information provided, the velocity after 2 seconds is 11 m/s.
From the equations of motion;
v = u + at
Where;
v = final velocity
a = acceleration
t = time taken
The initial velocity of the bike was 7 m/s and its acceleration is 2 m/s2. This change occurred within a time of 2 seconds.
Hence;
v = 7 + 2(2)
v = 11 m/s
The velocity after 2 seconds is 11 m/s.

A student pushes a chair into a desk. If the student's push is the action force, then what is the reaction force in this example of Newton's third law?
A. the force that the chair exerts on the desk after it is pushed in
B. the force of friction acting on the chair
C. the force of gravity acting on the chair
D. the force from the chair on the student
Answer:
Ans : C
Explanation:
C. The force of gravity acting on the chair
Answer:
D. the force from the chair on the student
Explanation:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

Describe three characteristics of electromagnetic waves that make them useful for transmitting signals.
Answer:
characteristics of electromagnetic waves:-
electromagnetic waves are transverse waves;electromagnetic waves can travel through a vacuum;electromagnetic waves travel at exactly the same speed in a vacuum, the speed of light, 300,000,000 m/s.A characteristics Feature of electromagnetic waves that make them useful for transmitting signal is that they are easily transmitted through
In physics, electromagnetic radiation is defined as waves created as a result of the electromagnetic field vibratons moving through space, carrying electromagnetic energy. The waves produced includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays.
The character of an electromagnetic wave is dependent on its frequency or wavelength making each electromagnetic spectrum having their own range of uses.
For transmitting signals, Radio waves as well as Microwaves is useful , while the former help transmit Information through radio and TV stations the later is used in satellite communications, this is because
They are easily transmitted through air. if absorbed by the human body, cannot cause damageThier directions can be changed or switched.See more here:https://brainly.com/question/877487
In Greenland there is a glacier called the Jakobshavn Isbrae that moves more quickly than any other
glacier known to mankind. It travels 8.2 millimeters every day. How far does the glacier move in a YEAR?
Convert units and show your work. (HINT-> how many days are there in a year? How many millimeters
in a meter?)
Answer:
8.2 mm / day * 1 m / 1000 mm = .00082 m / day distance in 1 day
365 day / 1 yr * .00082 m / day = .30 m / yr
How is water cleaned in chongqing?

Explanation:

can you please explain this answer?
Answer:
Final velocity = 7.4m/s
Explanation:
Use the equation:
acceleration = (final velocity - initial velocity)/time
Rearrange to get:
final velocity = (acceleration * time) + initial velocity
Now just substitute with the values you already have:
Final velocity = (-9.8m/s^2 * 0.7s) + 0.5m/s
Final velocity = 7.36m/s
We are using 2 sig-figs, so:
Final Velocity = 7.4m/s

what force is needed to make a ball fall on earth if it had a mass of 13kg
I'd appreciate if someone could help me thank you
Newton's second law allows finding the answer for the force that attracts the body is 127.4N
Newton's second law indicates that the force that is the interaction between two bodies is directly proportional to the product of the mass and the acceleration.
F = m a
Where the bold letters indicate vectors, F is the force, m the mass, and the acceleration of the body.
When a body is close to the Earth there is an interaction between the body and the planet, we call this interaction weight, it is given by the relationship
W = m g
Where W is the force called weight, m the mass of the body and g the acceleration of the body, which in this case is called the gravity acceleration (g = 9.8 m / s²)
They indicate that the mass of the body is m = 13 kg, let's calculate the weight
W = 13 9.8
W = 127.4 N
In conclusion using Newton's second law we can find the answer for the force that attracts the body is 127.4N

A 3000-kg spaceship is moving away from a space station at a constant speed of 3 m/s. The astronaut in the spaceship decides to return to the space station by switching on engines that expel fuel so that the sum of the forces exerted on the spaceship by the expelled fuel points toward the space station. What is the magnitude of the minimum force needed to bring the spaceship back to the space station
Answer:
P = m (v2 - v1) change in momentum
P = - m v1 if v2 is to be zero
F = P / t change in momentum equals applied force
F = m a = - m v1 / t
a = -v1 / t or a * t = -v1`
Any combination of a and t that is greater than v1 will bring the space station to a halt
If a is small then t must be large
Any applied force will eventually bring the ship to a halt and then begin the acceleration towards the starting point

7.According to the periodic table, how many total particles are there in the nucleus of a Titanium, Ti, atom?
Answer:
there are 22 massive, positively charged, fundamental particles in the element's nucleus. Given this, the element is unquestionably titanium.
The nucleus of titanium contains 46 particles in total in which 22 protons and 26 neutrons.
What is atomic nucleus?The atomic nucleus can be described as the small and dense region containing of protons and neutrons at the center of an atom. An atom is made of a positively charged nucleus, with electrons surrounding it, bound together by electrostatic force.
Almost all of the mass of an atom is concentrated in the nucleus as the mass of electrons is negligible. Neutrons and Protons are bound together to create a nucleus by the nuclear force.
The diameter of the nucleus is about 1.70 fm for hydrogen to about 11.7 fm for uranium. Protons and neutrons are fermions, are the particles present inside the nucleus.
The titanium has 22 protons and 26 neutrons in its nucleus so it has 46 particles in its atomic nucleus.
