Answer:
the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².
Explanation:
Given;
applied force, F = 5000 N
cross sectional area of the steel wire, A = 0.2 m²
The tensile stress of the steel wire, is calculated as;
Therefore, the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².
Answer:
The magnitude of the truck's velocity relative to the ground is 35.82 m/s.
Explanation:
Given that,
Velocity of car relative to ground = 15.3 m/s
Velocity of truck relative to car = 22.5 m/s
We need to calculate the magnitude of the truck's velocity relative to the ground
We need to calculate the x component of the velocity
We need to calculate the y component of the velocity
Using Pythagorean theorem
Hence, The magnitude of the truck's velocity relative to the ground is 35.82 m/s.
Answer:
The answer is below
Explanation:
Charles law states that the volume and temperature of a fixed amount of a gas is directly proportional to each other provided that pressure is held constant.
Boyle's law states that the volume and pressure of a fixed amount of a gas are inversely proportional to each other provided that temperature is held constant.
a) Constant property:
In Charles law, pressure is kept constant while in Boyle's law, temperature is held constant.
b) Varying properties:
In Charles law, volume and temperature are varying while in Boyle's law, pressure and volume are varying.
c) Type of variance:
In Charles law we have a direct variance while in Boyle's law we have an indirect variance.
d) Charles law is given as:
Boyle's law is given as:
