Answer;
= 13.33 m/s²
Solution;
From the second Newton's law of motion;
F= ma
F is the force = 40 N
M is the mass = 3 kg
a is the acceleration;
40 = 3 × a
a = 40/3
= 13.33 m/s²
Hence; the maximum acceleration the bag can withstand before ripping is 13.33 m/s²
The electron and positron collide and annihilate each other, converting their total energy (sum of kinetic and rest energy) into energy carried by two photons:
2(1.64MeV + 0.511MeV) = 2
= 1.64MeV + 0.511MeV
= 2.15MeV
Water evaporates at 100⁰C
So change in temperature = 100-20 = 80⁰C
Amount of water to be evaporated = 1 liter = 1L*1kg/liter = 1 kg
Specific heat of water is 1 calorie/gram ⁰C = 4.186 joule/gram =4186 J/kg
So heat required E = mcΔT = 1 * 4186 *80= 334880 J =334.88 kJ
So amount of heat require to evaporate water = 334.88 kJ

Explanation:
If Team A is on the left, B is on the right
if the force is constant, it means that the effort applied is equal.
So Team B is pulling 5000N to the right.
