Answer:
With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down. How much it slows the object down depends on the surface area of the object and its speed

Answer:
975 m/s^2
Explanation:
The formula for rate of acceleration is
(Final velocity - intial velocity)/ time taken
If you plug in your data you will get 975 m/s^2
(1600 m/s -1210 m/s )/.4 s = 975 m^2
Answer:
1)
Force on bar magnet = 0
Torque on bar magnet = 0
2)
Force on bar magnet = 0
Torque on bar magnet = 0.177 Nm
3)
Force on bar magnet = 0
Torque on bar magnet = 0.25 Nm
Explanation:
Part 1)
net force on bar magnet in uniform magnetic field is always zero
Torque on bar magnet is given as
when bar magnet is inclined along z axis along magnetic field
then we will have
Part 2)
net force on bar magnet in uniform magnetic field is always zero
Torque on bar magnet is given as
when bar magnet is pointing 45 degree with z axis then we will have
Part 3)
net force on bar magnet in uniform magnetic field is always zero
Torque on bar magnet is given as
when bar magnet is pointing 90 degree with z axis then we will have
Answer:
P=mv 2250*25=56250
Explanation:
p of truck =2250*25 =56250
since p of truck = p of car
then p of car = 56250
therefore p of car = 1210 * v
or, 56520=1210v
or,v= 56520/1210=46.48
so, v of car is 46.48m/s
Answer:
E
Explanation:
Using Coulomb's law equation
Force of the charge = k qQ /d²
and E = F/ q
substitute for F
E = ( K Qq/ d² ) / q
q cancel q
E = KQ / d²
so twice the distance of the from the point charge will lead to the E ( electric field ) decrease by a 4 = E/4. E is inversely proportional to d²
