Chameleon's tongue is more fast than thought. Its long sticky tongue moves at an amazing ballistic speed which lashes out unsuspecting insects and bugs. Now let us see how fast it is.
GIven:
acceleration of the chameleon's tongue- 260 m/s
2 for 20 ms
constant speed 30 ms
50 ms total time
1/20 of a second
solution:
<u>260</u> = <u> n</u><u> </u>
20 50
<u>20 n </u>= <u>13, 000</u>
20 20
n= 650 m/s

Answer:
A Pareto chart, named after an Italian economist, combines a bar chart with a line graph. The bar chart is different from a histogram in more than one way. For example, the vertical bars need not touch one another as per a histogram
Explanation:
Answer:
Average speed of Olympic runner will be 23.08 km/hr
Explanation:
We have given distance d = 27.3 miles
We know that 1 mile = 1.6 km
So 27.3 mile = 
Given time = 2 hour 45 minutes and 35 sec
We know that 1 hour = 60 minutes
So 45 minutes 
We also know that 1 hour = 3600 sec
So 1 sec 
So total time t =
We know that speed 
Answer:

so each bulb brightness becomes half of its given or indicated power

so both bulb will glow same power as indicated
Explanation:
Let the indicated power on the bulbs is given as P and its rated voltage is V
so here resistance of each bulb is given as

now if the two bulbs are connected in series so we will have


now the current in the circuit is given as


now brightness of each bulb is given as


so each bulb brightness becomes half of its given or indicated power
Now if the two bulbs are connected in parallel
then the net voltage across each bulb is "V"
so we will have

so both bulb will glow same power as indicated
