A seems wrong because with 20 N the can should go more than .5 m so I would say the awnser is B
Hope I Helped :)
Answer:
<em>An object is said to be rated </em><em>1 Watt </em><em>when it performs a work worth </em><em>1 Joule </em><em>in </em><em>1 second.</em>
Explanation:
<em>We know that power is rate of doing work or Work done in a given period of time.</em>
<em>Power is simply given by the formula:</em>
<em>Power=(Work)/(Time)</em>
<em>The SI unit of Power, Work and Time are Watts, Joules and Seconds respectively.</em>
<em>Hence, 1 Watt=1 Joule/ 1 Second</em>

As per the problem, the charge is of 2.5μC, moving in magnetic field T and having velocity m/s, the force comes out to be 3.75N
<h3>
what is magnetic force?</h3>
Magnetic force is the force experienced by the object inside the magnetic field or flowing current across the conductor. This force is caused due to the movement of charges.
The force exerted is magnetic force which is given as,
here,
Q= charge
v= velocity
B= Magnetic field and
=Angle of object from magnetic field

Answer:
Their velocity is 0m/s because the first box was only 10 kg and the second box was double the weight
Answer:
acceleration a = 1,557 m/s²
Explanation:
Let's use the kinematic equations, the initial distance is 70 m (Xo = 70 m), also if the track is 2200m long or 100m long when clearing use a distance in the path of
X = 2200-100-70 = 2030 m
With this data let's calculate the acceleration
Vf² = Vo² + 2 a X
the jet leaves the rest (Vo=0=
a = Vf2 / 2X
a = 80 2/2 2030
a = 1,557 m/s²
