Why roads are banked in hill stations

Answer»

If the road is banked, so that the OUTER EDGE is above the inner edge, then a portion of the NORMAL force from the road on the tires points towards the CENTER of the track; this FRACTION of the normal force can provide enough centripetal force to keep the car moving in a circle.

What is the derivation of v²= u²+ 2as?​

Answer»

v*2 = u*2 +2asSo now we have the eq.v = u +ats = 1/2 (u+v) ts = it + 1/2 at*2All three have t in them - it would be USEFUL to get RID of it. STARTING with the first eq. we can write: t = (v- u ) ÷a.this can be substitute d into second:s = 1/2( u+v) ts= 1/2 ( u+v) (v-u) ÷aExpanding the brackets , and multiplying out the 1/2 & a :2as = (u+v) (v-u) this rearranges to: v*2 = u*2 +2as

The speed of sound in air at 0°C is 332 m/s. If it increases at the rate of 0.6 m/s per degree,what will be the temperature when the velocityhas increased to 344 m/s?​

Answer»

The SPEED of SOUND in air at 0℃ = 332m/sNow, If it increases at the rate of 0.6m/s per DEGREE,Then, Speed at x℃ = (332 + 0.6x)℃Thus, 344 = 332 + 0.6x ⇒ 344 - 332 = 0.6x ⇒ 12 = 0.6x ∴ x = \frac{12}{0.6} = 20℃

the force between+1micro C and +1 mC charges which kept at a distance 1m is 9N in the vacuum.but if the same two charges kept inside the coconut oil,the force is 3.180N.whats the dielectric constant

Answer»

he force between+1micro C and +1 mC charges which kept at a distance 1m is 9N in the vacuum. But if the same TWO charges kept inside the coconut oil,the force is 3.180N.To FIND:What is the dielectric CONSTANT?Solution:From the GIVEN information, we have the data as follows.The force between+1micro C and +1 mC charges which kept at a distance 1m is 9N in the vacuum. But if the same two charges kept inside the coconut oil,the force is 3.180N.⇒ f = 9 N⇒ f_m = 3.18 NThe dieletric constant in terms of the ratio of forces is given as follows.k = f_m/fk = 3.18/9k = 0.35Therefore, the dielectric constant is 0.35.

2 tuning forks A and B are sounded together , producing beats of frequency 10Hz .if a small piece of plasticine is affixed onto fork B the beat decreases .if A has a frequency of 300Hz what is the original frequency of B?

Answer»

310Explanation:as beat 10 so B MAY be 310 or 290 , now when some thing attached to it it's frequency decrease as mass increase, so as frequency decrease so let suppose frequency decreased 2 hz so if it is 290, it will be 288 now you can see beat is 12 that means it INCREASES. but if 310 then it will 308 and beat will 8 , decrease .so it is 310
