It takes 5.0 J of heat in increase the temp of a sample by 10 degrees Celcius. If the mass is doubled, how much heat in joules w
ill it take to increase the temp by 10.0 degrees.a. 50.0 Jb. 5.0 Jc. 10.0 Jd. 15.0 J
1 answer:
Answer:
c. 10.0 J
Explanation:
The heat (Q) needed to increase the temperature of a certain mass of a sample can be calculated using the following expression:
Q = c . m . ΔT
where,
c is the heat capacity
m is the mass
ΔT is the change in temperature
Let's call Q₁ (5.0 J) the heat to increase the temperature of the mass m₁ by ΔT = 10.0°C.
Q₁ = c . m₁ . ΔT
If the mass is doubled (m₂ = 2 m₁), the heat required is:
Q₂ = c . m₂ . ΔT = c . 2 . m₁ . ΔT = 2 . c . m₁ . ΔT = 2 . Q₁
Q₂ = 2 . Q₁ = 2 . 5.0 J = 10.0 J

Answer:
F = 50 N
Explanation:
Given data:
Mass of car = 250 Kg
Acceleration of car = 0.20 m/s²
Force required = ?
Solution:
Formula:
F = m×a
F = applied force
m = mass
a = acceleration
Now we will put the values in formula.
F = 250 Kg × 0.20 m/s²
F = 50 Kg.m/s²
Kg.m/s² = N
F = 50 N
51.86 grams would be in the container.
One ounce is an equivalent of 28.34 grams, so times that by 12.2
.
12.2 * 28.34 = 345.75.
Put the percentage into decimal form, so 15% would now be 0.15.
0.15 * 345.75 = 51.86.
