True.

Explanation:

Acceleration by definition change of velocity over time.
Now that the object is increasing 10 m/s every second, so it's acceleration is:

(10m/s)/(1s) = 10 m/(s*s) = 10 m/s^2

True.

Explanation:

Since acceleration is defined as the rate of change of velocity over time, it can be written as

a=(dv)/dt

or

a=(v-u)/t

If u is at rest, it will be 0, and the equation becomes

a=v/t

In here, v=10m"/"s, t=1s

So,

a=(10m"/"s)/s=10m"/"s^2

In other words, the object's velocity will increase by 10m"/"s every second.
