The mass of an object that is experiencing a net force of 200 N and an acceleration of 500 m/s² is 0.4kg.
We know that, according to newton's second law of motion
F = m×a
here, F: force, m: mass of the object, a: acceleration
200 N = m × 500 m/s²
m = 200/500 kg = 2/5 kg
or m = 0.4 kg
Therefore, the mass of an object that is experiencing a net force of 200 N and an acceleration of 500 m/s² is 0.4kg.

Also, try inserting 8 in the blank.
4x+10+x=2.5(2x-4)
WITH SOLUTION PLEASEE AND I RLLY NEED IT RN thank u
Answer:
no solution
Step-by-step explanation:
4x + 10 + x = 2.5(2x - 4) ← distribute parenthesis
5x + 10 = 5x - 10 ( subtract 10 from both sides )
5x = 5x - 20 ( subtract 5x from both sides )
0 = - 20 ← not possible
this indicates the equation has no solution
Which name is given to a reaction in which the number of each type of atom on one side of the equation is equal to the number of
The same kind of atoms on the other side of the equation?
A balanced
B electrical
C complete
D atomic
Answer:
A balanced
Step-by-step explanation:
A reaction in which the number of each type of atom on one side of the equation is equal to the number of the same kind of atoms on the other side of the equation is called a balanced chemical equation.
It is a chemical equation that has the same number of atoms of each element on both sides of the equation. This is important because the law of conservation of mass states that matter can't be created or destroyed, so the number of atoms on one side of the equation must be equal to the number of atoms on the other side of the equation.
It is also important for calculating the stoichiometry of a reaction, determining the amount of reactants and products needed for a reaction, and to make sure that the chemical equation is in accordance with the laws of thermodynamics.
A small ring of mass 0.2 kg is threaded on a fixed vertical rod. The end A of a light inextensible string is attached to the ring. The other end C of the string is attached to a fixed point of the rod above A. A horizontal force of magnitude 8 N is applied to the point B of the string, where AB = 1.5 m and BC = 2m. The system is in equilibrium with the string taut and AB at right angles to BC (see diagram). The equilibrium is limiting with the ring on the point of sliding up the rod. (ii) Find the coefficient of friction between the ring and the rod.
The coefficient of friction between the ring and the rod is approximately 0.408.
STEPS TO FIND THE COEFFICIENTTo find the coefficient of friction between the ring and the rod, we can use the equation:friction = (force parallel to the surface) ÷ (force perpendicular to the surface)
In this case, the force parallel to the surface is the force of friction between the ring and the rod, and the force perpendicular to the surface is the weight of the ring. We can call this coefficient of friction as "µ"In order for the ring to be in equilibrium, the horizontal force applied at B must be balanced by the force of friction between the ring and the rod. So:F_horizontal = friction
F_horizontal = µ × F_perpendicular
8 N = µ × m × g
where m is the mass of the ring and g is the acceleration due to gravity.
Substituting the values, we have8 N = µ × 0.2 kg × 9.8 m/s²
µ = 8 N ÷ (0.2 kg * 9.8 m/s²)
µ = 0.408
So the coefficient of friction between the ring and the rod is approximately 0.408.

Given the line Y equals 3X -5 what is the same line given? Is it 3X minus Y equals five or 3X minus Y equals -5 or 3X plus Y equals 15 or 3XY equals -5 or X plus 3Y equals -15.
The line 5 = 3X - Y or3X minus Y equals five is the same line of Y equals 3X -5. The correct option is A.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given line:
Y equals 3X -5
Simplifying,
Y = 3X - 5
This is a linear equation.
To find the same line:
Y = 3X - 5
Taking constant to one side and variable to one side,
That means,
5 = 3X - Y
3X minus Y equals five

A company makes Poppy Lapel pins.
Answer:
the percentage profit of the company is 63.9%.
Step-by-step explanation:
Cost of making pins= £1.10
Number of pins= 1000
Total cost for making the pins
= Cost of each pin × Number of pins
= £1.10 × 1000
= £1110
Percentage of pins sold in charities
= 35% of 1000 pins
= (35/100) × 1000
= 350 pins
Left pins= 1000-350 = 650 pins
Number of pins sold at £3.00:
= 60% of 650
= (60/100) × 650
= 390
Selling price of these 390 pins
= 390 × £3.00
= £1170
Number of pins sold at £5.00 for 2:
= 40% of 650
= (40/100) × 650
= 260
These 260 pins were sold in pairs for £5.
Therefore, number of pairs sold
= 260/2
= 130 pairs
Selling price of these 130 pairs of pins
= 130 × £5.00
= £650
Therefore, total selling price
= £1170 + £650
= £1820
Profit by company
= Selling price - Cost price
= £1820 - £1110
= £710
Profit percentage
= Profit × 100 / Total cost price
= 710 × 100 / 1110
= 71000/1110
= 63.9%
