Number 4 I think
the atomic mass is 11 because the mass is the sum of protons and neutrons
Answer:
Astronomer
Explanation:
A scientist who studies the objects in the sky, including planets, galaxies, black holes, and stars, is called an astronomer. These days, the terms astronomer and astrophysicist are used interchangeably, to talk about any physicist who specializes in celestial bodies and the forces that affect them.
Answer: current I = 0.96 Ampere
Explanation:
Given that the
Resistance R = 60 Ω
Power = 55 W
Power is the product of current and voltage. That is
P = IV ...... (1)
But voltage V = IR. From ohms law.
Substitutes V in equation (1) power is now
P = I^2R
Substitute the above parameters into the formula to get current I
55 = 60 × I^2
Make I^2 the subject of formula
I^2 = 55/60
I^2 = 0.92
I = sqr(0.92)
I = 0.957 A
Therefore, 0.96 A current must be applied.
Answer:
like I see it as how well you're connected with yourself
Resistance can be calculated by Ohm's law
As per ohm's law we will have
![V = i * R](https://tex.z-dn.net/?f=%20V%20%3D%20i%20%2A%20R)
here we will have
voltage = 220 volts
current = 10 A
So by the above formula we will have
![220 = 10* R](https://tex.z-dn.net/?f=220%20%3D%2010%2A%20R)
![R = 22 ohm](https://tex.z-dn.net/?f=R%20%3D%2022%20ohm)
So resistance of the bulb is 22 ohm.
