A 12 m long uniform bridge weighing 100000 N is being supported at the two ends. A lorry weighing
30000 N is parked at the 4 m mark as shown in the
figure. What are the forces acting on the bridge by
support A and support B respectively?
| Support A | Support B | |
| A | 70000 N | 60000 N |
| B | 60000 N | 70000 N |
| C | 65000 N | 65000 N |
| D | 90000 N | 40000 N |
how ?

Yes it should be t/10 as the pendulum will pass through point y twice in its one revolution...... so the the time period should be t/10

it should be t/10 only as during time period the pendulum will pass through the point y twice.so the time period will be t/10
Ans 7:

it should be t/10 only as during time period the pendulum will pass through the point y twice.so the time period will be t/10
Ans 9:
Class : Class 6
throughout the time period or the 21 swings the pendulum will pass through the point Y 21 times. so the answer is B(t/21)
Ans 11:
Class : Class 6
It should be T/21 only as T is the total time and no of times it passes Y is 21.Therefore the answer is T/21
Ans 12:
Class : Class 8
it should be t/10 only as during time period the pendulum will pass through the point y twice.so the time period will be t/10
Ans 15:
Class : Class 8
Here, in this example, the pendulum passes through y 21 times. So, it will do 10 complete oscillations and 1 half which is basically touching y. Therefore, the time period of the pendulum is T/10.

Guys you are wrong process name is deposition but you need to cool it to water then freeze it
Ans 8:
Class : Class 9
Answer is B because to turn Water vapour into ice you need Deposition but water vapour cannot be deposited that is why you first need to turn the water vapour to water by condensation and then to convert water to ice you need freezing . Hence answer B is correct
Ans 17:
Class : Class 6
We can express process v as deposition and how did condensation and freezing get involved

The correct ans is option C because electrostatic force is a non contact force which is similar to magnetic force and the comb is like a magnet and tin pieces of paper are like the metal here (So the comb will attract the tiny pieces of paper).

Yes but in the question it said that the animal was imanginative can't believe what type of an animal it was.
Ans 28:
Class : Class 7
This is impossible cow only as four legs and two eyes and those two are not on the forehead
Ans 31:
Class : Class 5
I thought this could be an insect as it HAS SIX LEGS. And some spiders( I know they are not insects ) have more than two eyes so it could be possible that the correct answer is b. But it has fur and is feeding its young one milk so the answer should be d
