Answer:
7.59Ns
Explanation:
Given parameters:
Force = 1360N
Time of contact = 5.85 x 10⁻³s
Unknown:
Impulse = ?
Solution:
The impulse of the ball is given as:
Impulse = Force x time
Impulse = 1360 x 5.85 x 10⁻³ = 7.59Ns
The activation energy is 10 kJ and the reaction is exothermic.
Answer: Convection
Explanation: convection is the most present process in the refrigeration equipment you may deal with. It occurs mainly in the fluids
Mechanical advantage is the ratio of output force to input force of a machine.
hope this helps and have a great day :)
Answer:
Stellar Spectra Classification The patterns of lines detected in stellar spectra are used by astronomers to classify stars into spectral classes. These spectral classes are a measure of a star's surface temperature since the temperature of a star dictates which absorption lines are present in its spectrum.
