Answer:
A molecule is something every mass has and is very small
Explanation:
Answer:
mass is lifted 1.8 m. What is the potential energy of the mass 4. A 100 kg
Answer:
A. Light acts as particles, causing electrons on the surface it strikes to be destroyed.
Explanation:
- The photoelectric effect is a phenomenon that occurs when light shined onto a metal surface causes the ejection of electrons from that metal. It was observed that only certain frequencies of light are able to cause the ejection of electrons.
Answer:
The magnetic field strength inside the solenoid is
.
Explanation:
Given that,
Radius = 2.0 mm
Length = 5.0 cm
Current = 2.0 A
Number of turns = 100
(a). We need to calculate the magnetic field strength inside the solenoid
Using formula of the magnetic field strength
Using Ampere's Law

Where, N = Number of turns
I = current
l = length
Put the value into the formula


(b). We draw the diagram
Hence, The magnetic field strength inside the solenoid is
.
The chemical bonds alow it to pass to the other object.
