Pretty sure a, because it’s a stove and it uses electricity like almost a normal appliance for the kitchen would, the rest are just a natural force without any radiation to occur in them, electricity is the same as technology and believe it or not technology like phones give off radiation, so yeah. hope this was helpful!
In projectile motion we can say initial components of velocity is


now here horizontal motion is uniform motion as there is no force in this direction while in vertical direction due to gravity it will accelerate
so we have


so here we have x and y coordinates are related to each other as it will take same time to move the positions
so here correct options are
<em>Projectile motion is a combination of horizontal and vertical motion.
</em>
<em>The horizontal and vertical motions of a projectile are dependent on each other.</em>
Answer:
V at C is 3.6 m/s
Explanation:
At A kinetic energy is zero and potential energy=mgh=0.5*9.81*0.6=2.943 J
By conservation of energy.
KE+PE=Constant
At C PE=0.6 J
the KE=2.943-0.6=2.343 J
KE=0.5*m*v^2
v=√[KE/(0.5*m)]=3.06 m/s
Acceleration is the rate of change of velocity, and velocity is the change in displacement over the change in time so the answer would be A.
