The acceleration of the ball is 5 m/s^2. This can be calculated using a formula that relates the change in velocity, acceleration, and time. This formula is:
Vf = Vi + at
where:
Vf = final velocity
Vi = initial velocity
a = acceleration
t = time
Substituting the values gives:
30 = 20 + a(2)

Answer:
Speed is 1.962*10^-3m/s
Explanation:
Given that
Mass of proton==1.67*10^-27
Acceleration due to gravity (g)=9.81m/s^2
Angle of inclination A=90°
Charge (q)=1.6*10^-19
Magnetic field (B)=5*10^-5T
From lorentz force
It can be seen that
F=w =mg=qvBsinA
We're Velocity (v)=mg /qBsinA
V=1.67*10-27*9.81/1.6*10^-19*5*10^-5*sin90
V=1.962*10^-3m/s
F=ma so a=F/m
ax=180/270=0.67m/s^2
ay=390/270=1.44m/s^2
Magnitude = sqrt((0.67^2)+(1.44^2))=1.59m/s^2
Direction- Tan(x)=0.67/1.44=0.47 Tan^-1(x)=25 degrees
First and foremost, a photon is quantum of light. It is otherwise known as visible light and has a wavelength range of 400 to 700 nm. Moving waves are describable by their frequency (number of waves per second) and wavelengths.
A single photon can be considered unique from other photons only by its energy. In empty space (vacuum), all photons have the same speed or velocity.
The frequency of the electromagnetic vibration, we know as light, is given in units of Hertz. One hertz is equivalent to one vibration per second; it must be noted that the range of spectrum perceived by the eye extends from 4.3 x 10∧ 14 Hz in the red to about 7.5 x 10∧ 14 Hz in the violet.
Answer:
and direction
Explanation:
because when we definite force force is the pull or push of an object and when a force is exerted on the object it works 3 tasks 1, it multiply the force , 2, it multiply the speed, 3, it changes the directions so when we see a vector quantity is a quantity that have both magnitude and direction so when it multiply it's force and speed the object will have magnitude and when it multiply it's direction the object will have a direction. thank you for reading this explanation.☺☺☺☺
