The thermal energy of an object is the energy contained in the motion and vibration of its molecules. Thermal energy is measured through temperature. The energy contained in the small motions of the object's molecules can be broken up into a combination of microscopic kinetic energy and potential energy.
An increase in average speed of 1 km/h typi- cally results in a 3% higher risk of a crash involving injury, with a 4–5% increase for crashes that result in fatalities. — Speed also contributes to the severity of the impact when a collision does occur. Hope this helps!
Answer:
10 N
Explanation:
From the diagram,
Applying the principle of moment,
Sum of clockwise moment = sum of anti clockwise moment.
Assuming: the 10 N is placed on the 5 cm mark, F is placed on the 40 cm mark, The 25 N is placed on the 10 cm mark, the 30 N is placed on the 75 cm mark, and the 40 N is placed on the 80 cm mark.
Therefore,
10(50-5)+F(50-40)+40(80-50) = 30(75-50)+25(50-10)
450+10F+1200 = 750+1000
10F+1650 = 1750
10F = 1750-1650
10F = 100
F = 100/10
F = 10 N
Answer: They create antibodies.
