Answer:
Explanation:
From the equation given ; T(m)=21+74⋅10 −0.03m
Plugging the value of m = 10minutes for the time to calculate the temperature at that time instant. The detailed steps is as shown in the attached file

Answer:
1.76m/s²
Explanation:
Acceleration is the time rate of change in velocity of a body. It is a vector quantity that is it has both magnitude and direction
From newton's second law of motion which states that the rate of change of momentum of a body is proportional to the applied force which takes place in the direction of force applied.
This law gives a formula which relate force, mass and acceleration.
Force = mass x acceleration
Given that force = 9.7N , mass = 5.5kg
Since force(F)= mass(m) x acceleration(a)
Therefore F = ma
Divide both sides by m
F/m = ma/m
Therefore,
Acceleration (a) = F/m
Acceleration = 9.7N ➗ 5.5kg
Acceleration = 1.76m/s²
The S. I unit of acceleration is m/s²
