Answer:
Electric energy moves through the wire to the lamp's bulb. In the bulb, electric energy transforms into thermal energy and light energy.
Explanation:
-1.5 m/s^2 x 1.2 seconds = -1.8 m/s
It is a negative value which means the object slowed down. The object would have originally been going that amount more.
5.0 + 1.8 = 6.8 m/s
answer: 6.8 m/s
Answer:
-2.8 m/s²
Explanation:
Acceleration: This can be defined as the rate of change of velocity The S. I unit of acceleration is m/s²
Using the equation of motion,
v² = u² + 2as................... Equation 1
Where v = Final velocity, u = initial velocity, a = acceleration, s = distance,
Given: v = 6.0 m/s, u = 8.0 m/s, s = 5.0 m.
Substituting into equation 1
6² = 8²+2(a)5
36 = 64 + 10a
10a = 36-64
10a = -28
10a/10 = -28/10
a = -2.8 m/s²
Note: a is negative because because the skater decelerate on the rough ice
Hence the magnitude of her acceleration is = -2.8 m/s²
Answer:
Then the cell won't be able to function properly. With no nucleus the cell will lose control. It won't know what to do and there will be no cell division.
Explanation:
Answer:
The answer is ""
Explanation:
For point a:
Energy balance equation:
From the above equation:
because the rate of air entering the tank that is constant.
Since the tank was initially empty and the inlet is constant hence,
Interpolate the enthalpy between . The surrounding air
temperature:
Substituting the value from ideal gas:
Follow the ideal gas table.
The and between temperature
Interpolate
Substitute values from the table.
For point b:
Consider the ideal gas equation. therefore, p is pressure, V is the volume, m is mass of gas. (M is the molar mass of the gas that is and R is gas constant), and T is the temperature.
For point c:
Entropy is given by the following formula:
