Answer:
v = 3 m/s
Explanation:
P is the momentum
m is the mass
v is the velocity
P = m•v
300 = 100•v Divide both sides per 100
300/100 = v
v = 3 m/s
Answer:
0.67 m/s
Explanation:
Mass of car 1, m₁ = 5000 kg
Mass of car 2, m₂ = 10,000 kg
Initial speed of car 1, u₁ = 2 m/s
Final speed of car 2, u₂ = 0 (at rest)
We need to find the final velocity of both cars when inelastic collision occurs. The momentum will remain conserved in case of inelastic collision. Using the conservation of momentum. Let V is the final speed.
So, after the inelastic collision, they will move with a speed of 0.67 m/s.
Answer:
Maximum possible voltage without shock across the thumb and index finger with a dry-skin = 33.88 V
Maximum possible voltage without shock across the thumb and index finger with a wet-skin = 0.135 V
Explanation:
From Ohm's law
V = IR
For the maximum possible voltage without shock for dry skin, the
R = 4.4 × 10⁵ Ω
I ≤ 77 μA
I ≤ 77 × 10⁻⁶ A
V ≤ 4.4 × 10⁵ × 77 × 10⁻⁶ = 33.88 V
For the maximum possible voltage without shock for dry skin, the
R = 1750 Ω
I ≤ 77 μA
I ≤ 77 × 10⁻⁶ A
V ≤ 1750 × 77 × 10⁻⁶ = 0.13475 V
Yes a igneous rock can be changed into another igneous rock. the reason behind it is when rocks melt they become magma or lava. when lava flows on the surface of the earth it crystallizes quickly and makes small crystals. but when they cool slower they make larger crystals. yes igneous rocks can change but only through extreme temperatures.
Answer:
Ionic radius is greater than atomic radius in an anion.
