As the car comes to rest it’s final velocity v will be 0
So our information g is
u = 12 m /s
t = 20s
v = 0
So acceleration is v-u/t
So 0-12/20
= -12/20
= -0.6 m / s^2
S= ut + 1/2 at^2
S = 12 x 20 + 1/2 x -12/20 x 400
S= 240 - 120
S = 120
It travels 120 m during the time interval.

Answer:
Energy = 21.42 Joules
Explanation:
Given the following data;
Charge = 2.38 C
Potential difference, v = 9 V
To find the energy gained;
Mathematically, it is given by the formula;
Energy = charge * potential difference
E = 2.38 * 9
E = 2.38 * 9
E = 21.42 Joules
Answer:
Explanation:
we know that for ideal gag we have
pV =nRT
Since volume, gas constant R and T are constant, so we have
![\frac{p}{n] = constant](https://tex.z-dn.net/?f=%5Cfrac%7Bp%7D%7Bn%5D%20%20%3D%20constant)
n = 0.289 mole
hence mass removed
Answer:
They are malleable.
Explanation:
Malleability is the property of metals that causes them to be able to be formed into thin sheets without breaking.
All metals are malleable.
The reason why metals are malleable is because the atoms in the metals have a stable structure and hence, when beaten, the atoms can move freely among each other and maintain their structure.
