Answer:
The work done is zero
Explanation:
No work is performed or required in moving the positive charge from point A to point B
Answer:
10 kg.m/s
Explanation:
Momentum is a product of mass and velocity, expressed as p=mv where m is the mass of an object, v is the velocity of an object and p denote momentum.
The principle of linear momentum states that the sum of momentum before and after collision are always equal.
Given mass of initially as 2kg and its velocitu as 5kg and taking forward direction as positive.
Momentum before collision will be
P=2kg*5m/s=10 kg.m/s
Answer:
Explanation:
Given ; P1 = 100 kPa, T1 = 30°C, T2 = 90°C, P2 = 200 kPa, V1 = 350 m/s
From energy conservation at inlet and outlet
h1 + (1/2)v1² = h2 + (1/2)v2²
CpT1 + (1/2)v1² = CpT2 + (1/2)v2²
.718(90-30) x 103= 0.5x (350²-v2²)
velocity at the exit of a diffuser ; V2=190.63m/s
the I'm pact force of 0.5 is lol u guys go and study why r u asking answers
