8.0 m/s if there is no air resistance. (B)
Less if there IS any air resistance.
Answer:
the position of the wood below the interface of the two liquids is 2.39 cm.
Explanation:
Given;
density of oil, = 926 kg/m³
density of the wood, = 974 kg/m³
density of water, = 1000 kg/m³
height of the wood, h = 3.69 cm
Based on the density of the wood, it will position across the two liquids.
let the position of the wood below the interface of the two liquids = x
Let the wood be in equilibrium position;
Therefore, the position of the wood below the interface of the two liquids is 2.39 cm.
Answer: A
Explanation:
Germanium, is atomic number 32, and if you add a proton, Germanium converts to arsenic. arsenic is very poisonous.
Answer:
The rate of change of an object's velocity is called acceleration.
The correct answer is option (3).
The horizontal component of the force pushing the skier in forward direction is 36.75 N or 37 N.
In Physics, force is defined as the effect that changes the direction of motion of an object or brings a moving object to halt.
In other words, a force is a pull or push which is applied to any object. It is a vector quantity and is measured in Newton (N).
The weight of the skier = 75 Kg
To find the horizontal component of force we will use the following information.
Frictional force due to ice, F = μN
Normal force N = mg = 75 x 9.8 = 735 N
Now let's calculate the Frictional force = 0.05 x 735 = 36.75 N
We know that the value of Coefficient of friction (μ) for ice is 0.05.
