Answer:
Difference between tangential and angular acceleration are mentioned in points.
Explanation:
We have to find the difference between tangential and angular acceleration:
Tangential acceleration :
- Its function is to change the magnitude of velocity.
- Defined as rate of change of linear speed.
- Formula
Angular acceleration :
- Its the rate of change of angular acceleration.
- Its value is same for different location of the same body.
- It is also the ratio of tangential acceleration and Radius.
- Formula and
The input voltage is 120 V and the transformer is a step up transformer due to increase in the voltage induced in the secondary coil.
<h3>
Input voltage </h3>
The input voltage of the transformer is the voltage of the primary coil and it is calculated as follows;
Ns/Np = Es/Ep
where;
- Ns is the number of turn in the secondary coil
- Np is the number of turn in the primary coil
- Es is the secondary voltage
- Ep is the primary voltage
2X/X = 240/Ep
2 = 240/Ep
Ep = 240/2
Ep = 120 V
Thus, the transformer is a step up transformer due to increase in the voltage induced in the secondary coil.

According to Newton's 2nd law of motion:
F = m * a where F is the force applied in Newtons, m is the mass of the object in kg, and a is the acceleration of the object in m/
.
Therefore the force applied in this situation is simply:
F = 6 kg * 2.3 m/
= 13.8 N
Hope this helps!
Answer:
3 outcomes
Explanation:
Since the sum must be less than 7, then one of them cannot be 7 because 7 + something > 7. Also the minimum number is 2 so one of them cannot be 5 either because 5 + 2 = 7 is not less than 7.
So the only options we have here is 2 and 4. The outcome of this is
(2,2) so 2 + 2 = 4 < 7
(2,4) so 2 + 4 = 6 < 7
(4,2) so 4 + 2 = 6 < 7
Note that (4,4) is not possible because 4 + 4 = 8 > 7
So 3 outcomes have a sum less than 7 and contain at least one even number
Answer:
Angular acceleration = 5 rad /s ^2
Kinetic energy = 0.391 J
Work done = 0.391 J
P =6.25 W
Explanation:
The torque is given as moment of inertia × angular acceleration
angular acceleration = torque/ moment of inertia
= 10/2= 5 rad/ s^2
The kinetic energy is = 1/2 Iw^2
w = angular acceleration/time
=5/8= 0.625 rad /s
1/2 × 2× 0.625^2
=0.391 J
The work done is equal to the kinetic energy of the motor at this time
W= 0.391 J
The average power is = torque × angular speed
= 10× 0.625
P = 6.25 W
