The car has gravitational potential energy (Eg)
Eg = mgh
Eg = (53kg) (9.81N/kg) (14m)
Eg = 7 279.02 J
Answer:
17.27m/s
Explanation:
M1U1 + M2U2 = (M1+M2)V
(900x15) + (750 x 20) = (900+750)V
13500+15000 = (1650)V
28500 = 1650v
V = 28500/1650 = 17.27m/s
V = 17.27m/s
Answer:
The answer is False.
Explanation: The FDA (food and drug administration) is a regulatory agency of the United state Government, they regulate the production and distribution of food and drugs within the United States of America, ensuring that standards are met and followed.
Most of the approvals given to food and drugs by FDA are done based on random sampling of products which may not be able to capture all the defective products in a given lot or batch of supplies, which is why it very necessary to take other measures to verify the wholesomeness, authenticity etc of a given product before purchasing or making use of such products.
Three different units of energy is
1. Joule: is is SI unit of measuring thermal energy or heat
2. Calorie: this system of energy is used when we take CGS system of mass and specific heat capacity
3. BTU: this system is known as british thermal unit which is used in measuring engineering calculations
