Using the formula
V1P1=V2P2
where V1=1.0
V2=4.0
P1=1.2
P2=?
P2=V1P1/V2
P2=1.0*1.2/4.0
P2=0.3 atm
Answer:
this raise the temperature is x = 3
Explanation:
Heat capacity is the relationship between heat and temperature change
C = Q / ΔT
if the heat in the system is given by the change in energy and we carry this differential formulas
= dE / dT
In this problem we are told that the energy of thermal radiation is
E = A V T⁴
Let's look for the specific heat
c_{v} = AV 4 T³
the power to which this raise the temperature is x = 3
Answer:
The force is
Explanation:
Given that,
Mass of car = 64 kg
Suppose, a 1400-kg car that stops from 34 km/h on a distance of 1.7 cm.
We need to calculate the acceleration
Using formula of acceleration
Where, v = final velocity
u = initial velocity
a = acceleration
s = distance
Put the value into the formula
We need to calculate the force
Using formula of force
Negative sign shows the direction of the force is in the direction opposite to the initial velocity.
Hence, The force is
