Answer: 18*22=396
Explanation:
18*22=
(10*22) + (8*22)=
220+176=396
Answer:
So option (b) will be correct option
Explanation:
We have given that there is a step up transformer in which number of turns in primary coil is 15
That is,
Primary voltage , and secondary voltage
We have to find the number of turns in the secondary \
We know that for the transformer
So option (b) will be correct option
Answer:
hot
Explanation:
cause the room temperature is higher
The net force acting on the child is 200N.
When two or more forces are acting on the system of objects, then the to attain equilibrium, net force must be zero.
The net force acting on the child will be
Net force = Sum of all the individual force with sign
Net force = -100 + 0 + 100 +200
Net force = 200 N.
Therefore, the net force acting on the child is 200 N.

Answer:
make use of a semi-formal letter
Answer:
1.6 m/s2
Explanation:
Let be the gravitational acceleration of the moon. We know that due to the law of energy conservation, kinetic energy (and speed) of the rock when being thrown upwards from the surface and when it returns to the surface is the same. Given that stays constant, we can conclude that the time it takes to reach its highest point, aka 0 velocity, is the same as the time it takes to fall down from that point to the surface, which is half of the total time, or 4 / 2 = 2 seconds.
So essentially it takes 2s to decelerate from 3.2 m/s to 0. We can use this information to calculate
So the gravitational acceleration on the Moon is 1.6 m/s2
