Answer:
3.85 percent
Explanation:
From the question,
Percentage error = (error/actual)×100................ Equation 1
Given: actual center of mass = 15 cm, error = 15.6-15 = 0.6 cm
Substitute these values into equation 1
Percentage error = (0.6/15.6)×100
Percentage error = 3.85 percent
Hence the percentage error of the uniform mass = 3.85 percent
Answer:
At elevated altitudes, any cooking that involves boiling or steaming generally requires compensation for lower temperatures because the boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure.
Explanation:
Answer:
The entropy change is 45.2 kJ/K.
Explanation:
mass of water at 100 C = 2 kg
Latent heat of vaporization, L = 2260 kJ/kg
Heat is
H = m L
H = 2 x 2260 = 4520 kJ
Entropy is given by
S = H/T = 4520/100 = 45.2 kJ/K
Answer:
Lift is the upward force on the wing acting perpendicular to the relative wind and perpendicular to the aircraft's lateral axis. Lift is required to counteract the aircraft's weight.
Explanation:
Answer:
The kinetic energy will be "399.65 J".
Explanation:
Given:
Mass,
m = 1.2 kg
Velocity,
v = 31.3 m/s
The total energy of mass will be:
⇒ 
or,
⇒ 
By putting the values, we get
Since,
The system's total energy is unchanged, then
⇒
or,
⇒
