Answer:
a_total = 2 √ (α² + w⁴)
, a_total = 2,236 m
Explanation:
The total acceleration of a body, if we use the Pythagorean theorem is
a_total² = a_T²2 +
²
where
the centripetal acceleration is
a_{c} = v² / r = w r²
tangential acceleration
a_T = dv / dt
angular and linear acceleration are related
a_T = α r
we substitute in the first equation
a_total = √ [(α r)² + (w r² )²]
a_total = 2 √ (α² + w⁴)
Let's find the angular velocity for t = 2 s if we start from rest wo = 0
w = w₀ + α t
w = 0 + 1.0 2
w = 2.0rad / s
we substitute
a_total = r √(1² + 2²) = r √5
a_total = r 2,236
In order to finish the calculation we need the radius to point A, suppose that this point is at a distance of r = 1 m
a_total = 2,236 m
One protons and also it grouped their because how it reacts with other materials such as other substances or materials

Answer:
375 and 450
Explanation:
The computation of the initial and the final temperature is shown below:
In condition 1:
The efficiency of a Carnot cycle is 
So, the equation is

For condition 2:
Now if the temperature is reduced by 75 degrees So, the efficiency is 
Therefore the next equation is

Now solve both the equations
solve equations (1) and (2)

T_2 + 450 = 75
T_2 = 375
Now put the T_2 value in any of the above equation
i.e
T_1 = T_2 + 75
T_1 = 375 + 75
= 450
Answer:-81.29 J
Explanation:
Given
mass of ball 
Length of string 
height of Room 
Gravitational Potential Energy is given by

where h=distance between datum and object
here Reference is ceiling
therefore 
Potential Energy of ball w.r.t ceiling

i.e. 81.29 J of Energy is required to lift a ball of mass 2.35 kg to the ceiling
