Answer:
The time it takes the proton to return to the horizontal plane is 7.83 X10⁻⁷ s
Explanation:
From Newton's second law, F = mg and also from coulomb's law F= Eq
Dividing both equations by mass;
F/m = Eq/m = mg/m, then
g = Eq/m --------equation 1
Again, in a projectile motion, the time of flight (T) is given as
T = (2usinθ/g) ---------equation 2
Substitute in the value of g into equation 2
Charge of proton = 1.6 X 10⁻¹⁹ C
Mass of proton = 1.67 X 10⁻²⁷ kg
E is given as 400 N/C, u = 3.0 × 10⁴ m/s and θ = 30°
Solving for T;
T = 7.83 X10⁻⁷ s
Explanation:
Using Ohm's Law and a bit of substitution, we can use voltage divided by current to solve for resistance. Doing that, we'll get 6 Ohm.
"Lightyear" is a <em>distance</em> ... specifically, the distance that light travels
through vacuum in one year of 365 days.
It's equivalent to 9.454 x 10^12 kilometers, or 5.875 x 10^12 miles .
Answer:
162.5 m is the distance traveled by an object.
Explanation:
Given that,
An object's constant acceleration (a) is 
.
The time (t) it traveled is 5 seconds.
The object is at rest that is "initial velocity" (u) is 0 m/s.
To find the distance traveled use the below formula,
Where, "s" is distance traveled, "u" is initial velocity, "a" is acceleration and "t" is time taken.
Substitute the given values in the above formula,
s = 162.5 m
Therefore, distance traveled is 162.5 m.
