Answer: B is right
Explanation: Heat Q = m Cv ΔT = 3.0 kg · 4186 J / (kg·K) · 30 K≈ 376 740 J
Answer:
<em> The momentum of the body would be 13500 kg .m/sec</em>
Explanation:
What Momentum Entails
momentum is a property that is possed by all moving objects, it is a product of mass and velocity. A moving object has a magnitude which is the mass of the body and direction which is the velocity towards a certain direction, so it is a vector quantity
Step by Step Calculation
The momentum of a body can be gotten from the expression below;
p = m x v
where p is the momentum
m is the mass of the body = 1000 kg
v is the velocity = 13.5 m/sec
Given these parameters our momentum would be;
p = 1000 kg x 13.5 m/sec
p = 13500 kg . m/sec
Therefore the momentum of the body would be 13500 kg. m/sec
Answer:
H3PO4 + 5HCl → PCl5 + 4H2O
Explanation:
The marble's volume is equal to 1.2

Density= mass/volume
Mass= 3.05 Grams
Volume= 1.2 cm^3
3.05/1.2= 2.92 <span>g/mL</span>
