Explanation:
each grid corresponding 0.1s⁻¹.
0.2grid unit = 0.2×0.1 =0.02s⁻¹
distance of the star from telescope
d = 1/p
d= 1/0.02= 50 par sec
1par sec = 3.26 light year
1 light year = 9.5×10¹²km
3.26ly=3.084×10¹³km
d= 50×3.084×10¹³=1.55×10¹⁵km

Explanation:
4x+5g=9t
Momentum:
· Can be found by multiplying
mass by velocity.
· Used to calculate force that
acts or is moving.
· Records only instantaneous
effects of a force that acts on
the system.
Inertia:
· Calculated as the integral force
over said period of time.
· The value of the force is necessary
in order to calculate it.
· Records the effects of both the force
acting on the system and how long it
acts for.
Answer:
4 A
Explanation:
Firstly we need to calculate the equivalent resistance. Since, two resistors of 6 connected in parallel, so equivalent resistance will be given by,
1/R = 1/R1 + 1/R2
1/R = (1/6 + 1/6) Ω
1/R = (1 + 1)/6 Ω
1/R = 2/6 Ω
R = 6/2 Ω
<u>R = 3 Ω</u>
We know that,
V = IR
- <em>V</em> denotes p.d (12V)
- <em>I</em> denotes current
- <em>R</em> denotes resistance (3 Ω)
12 = I × 3
12 ÷ 3 = I
<u>4 Ampere = I</u>
The resultant of the forces is 29 N. Option D
<h3>What is the resultant force?</h3>
The resultant force is the force that acts in a given direction. Now we have two forces as enumerated in the question.
Thus;
Resultant = √(10)^2 + (20)^2 - [2 * 10 * 20 * cos (60 - 30))
Resultant = 29 N
Thus, the resultant of the forces is 29 N.
