If 50 identical light bulbs are connected in series across
a single power source, then the voltage across each bulb
is ( 1/50 ) of the voltage delivered by the power source.
Answer:
Explanation:
Usually the angle between the y axis and x axis is 90° and we know that for furthest travel the degree angle must be 45° with the horizontal, Mo must release the ball about halfway between straight ahead and straight up
First of all the project motion is in the form of a parabolic path and it is a common practice that a paper airplane always follow a parabolic path, whenever it is thrown in the air, and gravity is acting upon the plane, like any other projectile.
Answer:
A beta emission(negatron)
Explanation:
1. A negatron resembles an orbital electron. It is represented as β⁻.
A negatron has a mass number of 0 but with a charge of -1
The decay of C-14 to N-14 can be depicted below:
¹⁴₆C → ¹⁴₇N + ₋₁⁰e
Both the mass number and atomic number is balanced according to the reaction.
2. In an electric field, the emission produced would be deflected towards the positive pole because it is negatively charged.
Rearrange equation 2:
m = 20.3/v
Sub into equation 1:
466 = (20.3/v)v^2
466 = 20.3v
v = 466 / 20.3
v = 22.96 m/s
Use to find m:
m = 20.3 / 22.96
m = 0.8843 kg
Rounding:
v = 23.0 m/s to three significant figures.
m = 0.884 kg to three significant figures.
