Answer: 1/R = 1/R1 + 1/R2+ ...+ 1/Rn
R is resistance of system in which there are resistors R1, R2 , ... Rn parallel.
Answer:
3.66m/s^2
Explanation:
First, we need to find the friction which is F=u*N.
After that, find the resultant force by substarcting the friction from the forward force.
Lastly,using the formula F=ma, substitute in the known values of F and m to find a
Answer:
Attracting means pulling toward you and repelling means pushing away
Explanation:
Answer:
2.48 m/s
Explanation:
We can use the kinematic equation,
s = ut +½at²
Where
s = displacement
u = initial velocity
t = time taken
a = acceleration
Using the equation in vertical direction,
321 = 0×t +½×g×t², u = 0 because initial vertical velocity is 0
We get t = 8.01 s
Using the equation in the horizontal direction,
52 = u×8.01 +½×0×(8.01)²,. a = 0 because no unbalanced force act on object in that direction
So u = 2.48 m/s
