Magnitude of acceleration = (change in speed) / (time for the change) .
Change in speed = (ending speed) - (starting speed)
= zero - (43 m/s)
= -43 m/s .
Magnitude of acceleration = (-43 m/sec) / (0.28 sec)
= (-43 / 0.28) (m/sec) / sec
= 153.57... m/s²
= 1.5... x 10² m/s² .
Answer:
wowwwww grape no one will have carrot
Answer:
and unbalanced force
Explanation:
if balanced then the object will exert as much force as you are. its like pushing against a wall. and unblanced force is like pushing against a chair
The electric current amount will vary according to the resistance value when connected to a voltage of a power supply. If resistance is reduced, current will increase. So, if the resistance is infinite (open circuit), the current could be considered zero, or infinitesimal small, if the resistance is zero (of infinitesimal small), the current will tend to be the maximum the power supply can provide. Here is the case of the power supply capability, input resistance, capacity to hold and regulate the output voltage to a certain maximum current, etc. Normally when you short circuit (zero ohms resi
Mass defect is the difference of the mass of the constituent particles (protons and neutrons) of the actual mass of the nucleus. The mass of a nucleus is actually less than the mass of the protons and neutrons.
This is how you calculate it for this problem.
lithium - 7 => 3 protons and 4 neutrons
mass of 3 protons = 3 * 1.007276 amu = 3.021828 amu
mass of 4 neutrons = 4 * 1.008665 amu = 4.03466
=> mass of 3 protons + 4 neutrons = 3.021828 amu + 4.03466 amu = 7.056488
Mass defect = mass of 3 protons and 4 neutrons - atomic mass of lithium =
Mass defect = 7.056488 amu - 7.016003 amu = 0.040485 amu
