Answer:
15.2 m/s²
Explanation:
Acceleration: This can be defined as the rate of change of velocity. The S.I unit of acceleration is m/s²
From the question,
F-W = ma......................... Equation 1
Where F = Tension on the line, W = weight of the fish, m = mass of the fish, a = acceleration of the fish.
But,
W = mg........................ Equation 2
Where g = acceleration due to gravity.
Substitute equation 2 into equation 1
F-mg = ma
make a the subject of the equation
a = (F-mg)/m.................... Equation 3
Given: F = 150 N, m = 6 kg,
Constant: g = 9.8 m/s²
Substitute into equation 2
a = [150-(6×9.8)]/6
a = (150-58.8)/6
a = 91.2/6
a = 15.2 m/s²
Hence the minimum acceleration of the fish = 15.2 m/s²
Mechanical and Chemical. (Weathering and erosion)
Answer:
Voltage, V = 0.0524 volts
Explanation:
Thickness of the membrane, 
Electric field strength, 
We need to find the voltage across it. The relationship between the voltage, electric field and the distance is given by :
V = 0.0524 volts
So, the voltage across the thick membrane is 0.0524 volts. Hence, this is the required solution.
it's caused by a pressure that is large on the button of an object that it is on the top of an object submerged in a liquid.
Explanation:
This is why object appear to weigh less when immersed in a liquid. If the upthrust is greater than the weight of the object, the object will rise up through the liquid.
DescriptionElectric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative. Like charges repel and unlike attract. An object with an absence of net charge is referred to as neutral.
