Answer:
yes
Explanation:
The metal is closer than 20 cm to the magnet which is in the magnetic field.
Answer:
v =3.41 m/s
Explanation:
given,
mass of block 1 = 6 Kg
mass of another block 2 = 4 Kg
coefficient of friction = 0.3
Assuming 6 Kg block is attached to the spring of spring constant 350 N/m
and distance between the two block is equal to 0.5 m
using formula


U = 43.75 J
using conservation of energy
KE = U - f.d
where f is the frictional force acting



v =3.41 m/s
Answer:
Box 1 has more mass than box 2.
Explanation:
Box 1 has more mass than box 2, as it caused a greater affect in the change of speed of box 2. During a collision, the object with a lesser mass will be affected more, causing the velocity to change more. Because box one is greater than box 2, it caused a larger change in speed when they collided.
