Answer:
3 Ω
Explanation:
Recall that Voltage = Current x Resistance
We are given that voltage = 6.0V and Current is 2.0 A.
Substituting these into the equation:
Voltage = Current x Resistance
6.0 = 2.0 x Resistance
Resistance = 6.0 / 2.0 = 3 Ω
Answer:
Three, the liquid in the man's cup, the stove is solid, and the air around them is a gas
Explanation:
The body will take 20 seconds to cover a distance of 1000 m i.e. 1 km
Answer:
1. t = 3.27 seconds
2. y = 147.3 m
Explanation:
Newton's Laws of Motions.
y = v₁t + 1/2 at²
a = (v₂-v₁)/t
where
y = the vertical distance travelled
v₁ = the initial velocity
v₂ = the final velocity
t = the time
a = the acceleration
final velocity is equal to 0.
So, v₂ = 0.
a = (v₂-v₁)/t
a = (0-30)/t
a = -30/t
plugin values into the first equation:
y = v₁t + 1/2 at²
49 = 30t + 1/2 (-30/t)t²
49 = 30t -15t
49 = 15 t
t = 49/15
t = 3.27 seconds
2.
y = v₁t + 1/2 at²
a = -30/3.27
a = 9.2
y = 30(3.27) + 1/2(9.2) 3.27²
y = 147.3 m
