How much current will a 500 W vacuum cleaner draw if it has a resistance of 30Ω?
1 answer:
Answer:
Electric current, I = 4.08 A
Explanation:
We have,
Power of vacuum cleaner is 500 W
Resistance of vacuum cleaner is 30 ohms
It is required to find the current flowing through the vacuum cleaner. It can be calculated using the definition of power delivered. Its formula is given by :
I is electric current
So, the electric current flowing through the vacuum cleaner is 4.08 A.

Answer:
6N
Explanation:
Given parameters:
Pressure applied by the woman = 300N/m²
Area = 0.02m²
Unknown:
Force applied = ?
Solution:
Pressure is the force per unit area on a body
Pressure =
Force = Pressure x area
Force = 300 x 0.02 = 6N
Answer:
X-rays are commonly produced in X-ray tubes by accelerating electrons through a potential difference (a voltage drop) and directing them onto a target material (i.e. tungsten).
The incoming electrons release X-rays as they slowdown in the target (braking radiation or bremsstrahlung). The X-ray photons produced in this manner range in energy from near zero up to the energy of the electrons.
