If friction is acting along the plane upwards
then in this case we will have
For equilibrium of 100 kg box on inclined plane we have
also for other side of hanging mass we have
now we have
In other case we can assume that friction will act along the plane downwards
so now in that case we will have
also we have
now we have
<em>So the range of angle will be 23.45 degree to 37 degree</em>
Answer:Nazi skinhead code for Heil Hitler. H being the 8th letter of the alphabet, therefore HH=88.
Explanation:
-- <u><em>Current is measured in amps.</em></u> (You can use any symbol you want to represent current, but the most common one is " I ", not "Δ".)
-- <u><em>The relationship between current, voltage, and resistance is mathematically defined by Ohm's Law. </em></u>
-- <u><em>Current is the flow of electrons through a circuit.</em></u>
-- (Ohm's Law is NOT mathematically represented by the equation V=I/R.) <u><em>It should be V = I · R</em></u> .
(When solving for Resistance in a circuit and both voltage and current are known values, the equation I =V*R is not true, and not the way to solve it.) <u><em>If the resistance is what you're looking for, then the equation to use is </em></u><u><em>R = V / I</em></u><u><em> . </em></u>
<em>-- </em><u><em>If the voltage in a circuit is increased, the current will also increase.</em></u>
115.94g of O₂ are produced by 250g of Ca(ClO₃)₂
<u>Explanation:</u>
Ca(ClO₃)₂ -->CaCl₂ + 3O₂
One mole of calcium chlorate give three moles of oxygen.
Molar mass of calcium chlorate is
40+(35.5+16*3)*2 = 207g/mol
Molar mass of Oxygen = 32g
1 mole of calcium chlorate decomposes to form 3 moles of oxygen.
So,
207g of Ca(ClO₃)₂ produces 3 X 32g of O₂
250g of Ca(ClO₃)₂ will produce = 
= 115.94g of O₂
Therefore, 115.94g of O₂ are produced by 250g of Ca(ClO₃)₂
To start off.. add any and all the vectors acting on the same axis (x and y), making sure to pay attention to the director of the vectors. you are often able to ignore many of the forces that cancel each other out. make sure to focus on the forces that are actualy involved in how the object will move. Then you calculate the net force acting on the object in the situation
Since nothing is happening along the y-axis, you can ignore the Fg (300N)and FN (20N) forces.
FNET = Fa + Ff
= 80N + -70N
FNET = 10N
you have to make the friction a negative force
because it is pointing in the direction opposite to the applied force.
When you want to calculate the acceleration of an object, always use the net force acting on it.
you aren’t subtracting the two forces.
Instead, it’s up to you to remember that if one of the forces is pointing in one direction (like to the right), and the other force is pointing in the other direction (like to the left), you will need to make one positive and the other negative.
i don’t really know how to explain this super well. i hope this helps!!
