Answer:
Explanation:
The 3 kg box will have a downward force of its weight (Mg) and a balancing upward force of the normal force from the table. It will have a horizontal force T pointed towards the hanging mass side from the connecting cable.
The 2 kg hanging box will have a downward force of its weight (mg) and an upward force T from the connecting cable
Answer:
1000
Explanation:
because if you multiple times a 100 you will get a 1000
Answer:
R = 0.0015Ω
Explanation:
The formula for calculating the resistivity of a material is expressed as;
ρ = RA/l
R is the resistance
ρ is the resistivity
A is the area of the wire
l is the length of the wire
Given
l = 85cm = 0.85m
A = πr²
A = 3.14*0.0018²
A = 0.0000101736m²
ρ = 1.75 × 10-8Ωm.
Substitute into the formula
1.75 × 10-8 = 0.0000101736R/0.85
1.4875× 10-8 = 0.0000101736R
R = 1.4875× 10-8/0.0000101736
R = 0.0015Ω
Reading a digital thermometer is more preferable because you can just easily read the measurement from a screen, a number will just show in a screen as compared to a liquid-based thermometer where you still have to read the measurement by counting the markers in the thermometer. Hope this helps! Mark brainly please!
