You can use the Pythagorean theorem to calculate the hypotenuse, since the resultant is the hypotenuse of the triangle.

$r^{2} = x^{2} + y^{2}\\r^{2} = 12^{2} + 16^{2}\\r^{2} = 144 + 256\\r^{2} = 400\\r = \sqrt{400}\\r = 20N$

If one doubles the emfs in a circuit and doubles the resistances in the circuit at the same time, what happens to the currents t

bija089 [108]

Answer:

Same

Explanation:

Let R be the resistance of the cell and E be the emf.

Let i be the current in the circuit.

i = E / R ..... (1)

Now emf and resistance be doubled.

so, i' = 2E/2R = E/R

So, i' = i (From equation (1)

Current remains same.

Consider a car travelling at 60 km/hr. If the radius of a tire is 25 cm, calculate the angular speed of a point on the outer edg

KengaRu [80]

Answer

given,

speed of car = 60 km/hr

= 60 x 0.278 m/s

= 16.68 m/s

radius of the tire = 25 cm = 0.25 m

time taken to stop = 6 s

average acceleration = ?

$\omega = \dfrac{v}{R}$

$\omega = \dfrac{16.68}{0.25}$

$\omega =66.72 rad/s$

average acceleration= $\dfrac{\Delta \omega}{\Delta t}$

= $\dfrac{66.72}{6}$

= 11.12 rad/s²

correct answer option D

b) length of sea saw = 10 m

mass of jack = 100 Kg

mass of Jill = 60 Kg

Let y be the distance from the Jack. To balance the seesaw moment on both side should balance each other about fulcrum

now,

100 x y = 5 x 60

y = 3 m

the correct answer is option B
