We have that F=ma from the 2nd Newton law where F is the force, m is the mass and a is the acceleration. Suppose we have that F' is the new force and m' is the new mass. Then, we have that a'=F'/m' still, by rearranging Newton's law. We are given that F'=2F and m'=m/2. Hence,
a'= \frac{2F}{ \frac{m}{2} } = \frac{4F}{m} = 4\frac{F}{m}
But now, we have from F=ma, that a=F/m and we are given that a=1m/s^2.
We can substitute thus, a'=4a=4*1m/s^2=4m/s^2.

Many flashlights are powered by a stack of batteries that are slid into the end of the flashlight one after another. Suppose you
Basile [38]

Answer:

The current through the bulb when the flashlight is turned on is 0.55 A.

Explanation:

Given that,

You have a flashlight that takes four ideal 1.5 V batteries, voltage of the flashlight, V = 6 V

The resistance of bulb, R = 11 ohms

We need to find the current through the bulb when the flashlight is turned on. As per Ohms's law :

V = IR

I=\dfrac{V}{R}\\\\I=\dfrac{6\ V}{11\ \Omega}\\\\I=0.55\ A

So, the current through the bulb when the flashlight is turned on is 0.55 A. Hence, this is the required solution.
