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>
Answer:
1.28 m
Explanation:
You are given the initial speed that is 5 m/s. Since the coin is sent upwards, this means that the speed is positive according to the co-ordinate system in the y axis. Additionally, there is the gravity that curbs the coin in the opposite direction making the final speed becomes zero at the highest point, so the gravity takes negative sign.
So, from the explanation we have:
so, we use the following equation to find y (hight)

Explanation:
The calculated weight in newtons is 10 N.
Listed below is the data we will use:
Area A is where the pressure is P. Here are the details we were given:
A=1 cm2, P=101325 N/m, and w=?
Do the area conversion to square meters.
A=1cm2×1m2/1002cm2\s=1×10−4m2
From the definition of pressure, calculate the weight of the air column. In this instance, the air column's weight is determined by multiplying the atmospheric pressure by the air column's base area.
Fw = P atm A
= (101325N/m2) (1 10 4m2)
= 10N
The complete question is - Imagine a square column of the atmosphere, 1 cm on a side, that extends all the way to the top of the atmosphere. How much does this column of air weigh in newtons?
