For #5 It's helpful to draw a free body diagram so you know which way the forces are acting on the block.
the weight mg is acting downwards, and you need to find the vertical and horizontal components of mg using sin and cosine. so do 15x9.8xsin40 which is the force. Assuming no friction, this is the only force acting on the block, as the forces on the vertical plane cancel out i.e the normal force and weight of the block.
after, just do F=ma And since you know F and m, solve for a.
Answer:
0.075A
Explanation:
We can consider this system as a circuit, hence we can take the current from the formula for the electric power as follow
I hope this is useful for you
regards
When a current flows through coil, magnetic field is produced around the coil which induces emf also known as back emf. When current in the coil is increased, more magnetic field is produced which in turn increases the induced emf.
The second object, the one that had twice the force applied to it, would move twice as far, I believe.
As per momentum conservation theory
If net force on a system is zero then initial momentum of the system will be equal to final momentum of that system.
Since initially coconut is at rest so initial momentum is zero
Here it break into three pieces such that two parts of same mass while third part is of double mass
now we can say

here we know that two parts fly off with same speed v0 along south and west directions

now we will have

so here magnitude of the speed of the third part will be


and the direction of the third part will be along North East direction
