Answer:
1110 N
Explanation:
First, find the acceleration.
Given:
Δx = 300 m
v₀ = 85.5 km/h = 23.75 m/s
v = 0 m/s
Find: a
v² = v₀² + 2aΔx
(0 m/s)² = (23.75 m/s)² + 2a (300 m)
a = -0.94 m/s²
Find the force:
F = ma
F = (1180 kg) (-0.94 m/s²)
F = -1110 N
The magnitude of the force is 1110 N.
Sodium and potassium are positively charged ions called cations, and chloride and phosphate form negatively charged ions called anions. is true!
Answer:
C
Explanation:
An equilibrium is when all forces are the same or canceled out. So it would have to be c.
The resistance of the coil is 12. 97 Ω
<h3>How to determine the length</h3>
The formula for resistance is given as;
R = V/I
Note that resistance, R is measured in Ohms and represented with the symbol ( Ω)
Where;
- V is the voltage = 120 V
- I is the current = 9. 25 A
Substitute the values into the formula
R = 120/ 9. 25
R = 12. 97 Ω
The resistance, R is 12. 97 Ω
Hence, the resistance of the coil is 12. 97 Ω
