2.5 kg because you cant change the weight of the rock
Answer:
v = 7.67 m/s
Explanation:
Given data:
horizontal distance 11.98 m
Acceleration due to gravity 9.8 m/s^2
Assuming initial velocity is zero
we know that
solving for t
we have
substituing all value for time t
t = 1.56 s
we know that speed is given as
v = 7.67 m/s
His velocity is 3 m/s in the direction in which he is running in. which.
Answer:
16.6 kJ/°C
Explanation:
given,
Amount of heat absorbed = 45 kJ
initial temperature, T₁ = 25.5°C
final temperature, T₂ = 28.2°C
change in temperature = T₂ - T₁
= 28.2 - 25.5 = 2.7° C
Heat capacity of the object is equal to 16.6 kJ/°C
<h2>Energy remains constant </h2>
Explanation:
Thermodynamic Laws -
- The primary law, otherwise called the Law of Conservation of Energy, expresses that energy remains constant in the overall reaction, it is not created or destroyed.
- The second law of thermodynamics expresses that the entropy increases. after the completion of the reaction of any isolated system
- The third law of thermodynamics expresses that as the temperature reaches towards an absolute zero point the entropy of a system becomes constant.
Standard Electronic potential -
- The standard reduction potential may be defined as the tendency of a chemical species or the reactants to get into its reduced form after the overall reaction.
- It is estimated at volts.
- The more is the positive potential the more is the reduction of the chemical species
Aerobic grow is much more efficient at making ATP because of the presence of oxygen the cycles in the respiration are carried out at an efficient rate which forces the cell to undergo a much large amount of ATP production.
