Acceleration is defined as velocity per unit time.
![Acceleration=\frac{Velocity}{time}](https://tex.z-dn.net/?f=%20Acceleration%3D%5Cfrac%7BVelocity%7D%7Btime%7D%20)
![a=\frac{dv}{dt}](https://tex.z-dn.net/?f=%20a%3D%5Cfrac%7Bdv%7D%7Bdt%7D%20)
Here, a=acceleartion,
v=velocity=36 m/s
t=time=12 s
![a=\frac{dv}{dt}](https://tex.z-dn.net/?f=%20a%3D%5Cfrac%7Bdv%7D%7Bdt%7D%20)
![a=\frac{36}{12}](https://tex.z-dn.net/?f=%20a%3D%5Cfrac%7B36%7D%7B12%7D%20)
![a=3 ms⁻²](https://tex.z-dn.net/?f=%20a%3D3%20ms%E2%81%BB%C2%B2%20)
A car at rest ends accelerates for 12 seconds. After this time the car is going 36 m/s. So acceleration that is a=3 ms⁻².
Answer:
17 ohms
Explanation:
Given that,
In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance.
We need to find the total resistance of the circuit.
The equivalent resistance for series combination is given by :
![R_{eq}=R_1+R_2+....](https://tex.z-dn.net/?f=R_%7Beq%7D%3DR_1%2BR_2%2B....)
For 17 light bulbs, the equivalent resistance is given by :
![R_{eq}=R+R+....\text{upto 17 terms}\\\\R_{eq}=17R\\\\=17](https://tex.z-dn.net/?f=R_%7Beq%7D%3DR%2BR%2B....%5Ctext%7Bupto%2017%20terms%7D%5C%5C%5C%5CR_%7Beq%7D%3D17R%5C%5C%5C%5C%3D17)
Hence, the total resistance is 17 ohms. Hence, the correct option is (d).
Explanation:
The equation for the average is: (sum of all data values/ (total number of data values)
In chemical reactions, the actual yield is not the same as the expected yield . Actual yield is lower than the theoretical yield . Then we have to find the yield percentage. To see what percentage of the theoretical yield is the actual yield.
Percent yield = actual yield / theoretical yield x 100%
Percent yield = 24.6/55.9 x100%
Percent yield = 44%
