Answer:
2.64N
Explanation:
Force = mass * acceleration
Given
mass = 4kg
distance = 1.9m
Time t = 2.4s
Get the acceleration using the equation of motion
S = ut + 1/2at²
1.9 = 0 + 1/2a(2.4)²
1.9 = 5.76a/2
1.9 = 2.88a
a = 1.9/2.88
a = 0.66m/s²
Get the magnitude of the force
Force = 4 * 0.66
Force = 2.64N
Hence the net force acting on the fish is 2.64N
Answer:
acceleration and mass are inversely proportional values
Explanation:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Answer:
chemical energy is converted to electrical energy in a voltaic cell.
Answer:
0.006 m
Explanation:
d = separation between the slits = 0.150 mm = 0.150 x 10⁻³ m
λ = wavelength of the light = 643 nm = 643 x 10⁻⁹ m
D = distance of the screen where interference pattern is observed = 140 cm = 1.40 m
δ = Path difference
Path difference is given as
δ = Dλ/d
δ = (1.40) (643 x 10⁻⁹)/(0.150 x 10⁻³)
δ = 0.006 m
