Answer: B, they can land themselves now
Explanation:
Answer:
231.98 mL
Explanation:
V₁ = Initial volume = 205 mL
V₂ = Final volume
P₁ = Initial pressure = 712 mmHg
P₂ = Final pressure = 750 mmhg (STP)
T₁ = Initial temperature = -44 °C = 229.15 K
T₂ = Final temperature = 273.15 K (STP)
From Combined gas law
Volume of the argon at STP is 231.98 mL
Work = Force * distance
He's going up an incline but pushing parallel to the ground. Draw out a diagram to show what's going on. )
Work = force* distance*Cos(incline angle)
60 N force * 10 meters * cos(30)
= 519.61 J
When a wire is made shorter, the resistance decreases.
When a wire is made thinner, the resistance increases.
Answer:
Secondary current is 8A
Explanation:
Data :
Primary supply = Vp = 240 V
Secondary supply = Vs = 60V
Primary current = Ip = 2A
Secondary current = Is = ?
Formula : Vp × Ip = Vs × Is
So for secondary current formula becomes
Is = (Vp/Vs)×Ip = (240/60) × 2
Is = 4 × 2 = 8A
