Answer:
Uncountable stars, too many
Explanation:
The product of (mass) x (acceleration) is equal to (force).
So if (force) doesn't change and (mass) changes, then
(acceleration) has to change in the other direction from (mass)
in order to keep their product constant.
If the (forces) on both wagons are equal but one wagon has
double the (mass) of the other, then the more massive wagon
has (1/double) = 1/2 the acceleration of the less massive one.
Answer:
When the resistances are connected in the parallel the equivalent resistance will be always less than the value of the lowest resistance in the parallel circuit.
The equivalent resistance in the parallel circuit can be calculated using the following formula.
1/R=1/R1+1/R2+1/R3
1/R= 1/10+1/20+1/30
1/R=(6+3+2)/60
1/R=11/60
R=60/11
R=5.45 Ohms
Answer:
Step-by-step explanation:
i dont know man im getting nervos
Given :
Mass of block , M = 20 kg .
Force applied , F = 80 N .
Acceleration of block , 
.
To Find :
The coefficient is Kinetic force friction between the block and the table .
Solution :
We know , Force equation on block is given by :
Therefore , coefficient is Kinetic force friction between the block and the table is 0.15 .
Hence , this is the required solution .
