Answer:

Explanation:
Let say the ball is projected at an angle with horizontal
So here two components of the velocity of the ball is given as


now the displacement in x direction is given as


in y direction it is given as


now from above two equations




Answer:
Potential difference will be 151.9 volt
Explanation:
We have given capacitance of the capacitor 
Voltage V = 49 Volt
Dielectric constant K = 3.1
We have to find the potential difference
We know that when a dielectric medium is introduced then p[otential difference is increases by k times
As the dielectric constant k = 3.1
So potential difference will be = 3.1×49 = 151.9 volt
Answer:an electrical Current can be defined as the free flow of electrons through a circuit
Explanation:
Answer:
Part a)
A = 0.066 m
Part b)
maximum speed = 0.58 m/s
Explanation:
As we know that angular frequency of spring block system is given as

here we know
m = 3.5 kg
k = 270 N/m
now we have


Part a)
Speed of SHM at distance x = 0.020 m from its equilibrium position is given as



Part b)
Maximum speed of SHM at its mean position is given as


d. fishing
The other options all directly affect algal bloom production because they affect the nutrients in the water, and an overabundance of certain nutrients in the water is what causes algal bloom.
