Explanation:
The magnet requires almost direct <u>contact</u> with the fridge to start its magnetic properties.
Answer:
4000 km
Explanation:
as we know velocity of electromagnetic wave is c

frequency given (f) = 76 Hz
wavelength ?
using
λ
λ = 
λ =
≈4000 km
so final answer λ = 4000km
Not having clean water to drink or bath. Also some organizations that live in the water might die because the water is polluted and that would be toxic form them
length of the grilling machine is 1.2 m
time taken to cook the burger is 2.7 min = 162 s
so the speed of the machine should be like this that if must have to cook till it cross the machine



now in one minute the total length of the machine that is covered is given by


now distance between the burgers is 15 cm
so total production rate will be

so it will produce 3 burger per minute
Answer:
Maximum height reached by the ball is 32 meters.
Explanation:
It is given that,
If a baseball is project upwards from the ground level with an initial velocity of 32 feet per second, then it's height is a function of time. The equation is given as :
...........(1)
t is the time taken
s is the height attained as a function of time.
Maximum height achieved can be calculated as :


-16 t + 32 = 0
t = 2 seconds
Put the value of t in equation (1) as :

s = 32 meters
So, the maximum height reached by the ball is 32 meters. Hence, this is the required solution.
