Answer:
Explanation:
The equation for this is
where f is the frequency, v is the velocity, and lambda is the wavelength. Filling in:
and
which means that
the wavelength is 1.37 m, rounded to the correct number of significant digits.
The answer is B : F = 1.8 X 10 ∧ -15
Given:
Velocity of the proton: 2.0 × 10∧6 m/sec
Magnetic field strength(B): 5.5 × 10∧-3 tesla
Now it is given that velocity and the magnetic field are at 90 degree.
Also <u>Magnetic force F= qvBsin∅ </u>
where F is the magnetic force
q is the charge of the proton which is equal to 1.602x10∧-19 coloumbs
∅ is the angle between the v and B.
v is the velocity of the proton
B is the magnetic field
Substituting the values we get
F = 1.602 x 10 ∧-19 × 2.0 × 10∧6 × 5.5 × 10∧-3 Sin 90
F= 17.6 x 10 ∧-16 N
F= 1.76 x 10∧-15 N
Rounding off we get <u> F = 1.8 X 10 ∧ -15 N</u>
<u>Answer:</u>
The time taken for the ball to hit the floor as 1.02 seconds
<u>Explanation:</u>
As per the given question, the ball leaves at a speed from the table with an initial velocity of 10 m/s, we have the equation
where Vf represents the final velocity
Vi represents the initial velocity
a represents the acceleration and
t represents the time
after rearranging
= 1.022 seconds
Answer:
The motion of a projectile is a two-dimensional motion. ... This is called the principle of physical independence of motions. The velocity of the projectile can be resolved into two mutually perpendicular components: the horizontal component and the vertical component. Acceleration changes velocity.
