Answer:
11.0325 J
Step-by-step explanation:
The formula for calculating Potential Energy is:
P.E. = mass * acceleration due to gravity * height
where mass is in kg
acceleration due to gravity is a constant at the surface of the earth = 9.8 m/sec^2
and height is in meters
Here:
P.E. = 0.75 kg * 9.8 meters/sec^2 * 1.5 meters
P.E. = 11.0325 kg*m^2/sec^2
Now kg*m^2/sec^2 = joules
so the answer is 11.0325 joules
The required potential energy of the jar is 11.0325 joules.
What is potential energy?Potential energy is a form of stored energy that is dependent on the relationship between different system components. When a spring is compressed or stretched, its potential energy increases.
Given that,
The height of self h = 1.5 m.
The mass of cookie jar m = 0.75 kg.
To find the potential energy of jar,
Use formula of Potential Energy
Potential Energy = m × g × h
where m = mass is in kg
Ang g is gravity.
And the value of g at the surface of the earth = 9.8 m/sec²
and height is in meters
Substitute the values here,
Potential energy = 0.75 kg * 9.8 meters/sec² * 1.5 meters
Potential energy = 11.0325 kg x m²/sec²
Since, kg x m²/sec² = joules
Potential energy = 11.0325 joules.
Hence the required answer is 11.0325 joules.

A walkway forms one diagonal of a square playground. The walkway is 32 m long. How long is each side?
Answer:30.45751052, or 30.5
Step-by-step explanation:
since you know that the playground is a square, a diagonal would cut the square into 2 45-45-90 triangles, now that you know that information, there is a really easy way to solve the problem, the way i did it was i used the law of sines, which states that side a/sin(angle A)=side b/sin(angle B). so 32/sin(90)=30.7943... substitute that into the equation and you get 30.7943... =side b/sin(angle B). since you know that angle B =45 degrees take the sin of that and multiply it by 30.7943 to get the answer.

=> 2x = 5-3
=> 2x = 2
=> x = 2/2
=> x = 1
Therefore, the value of x is 1
Hope it helps :)
Answer:
x=1
Step-by-step explanation:
Hi there!
2x+3=5
Our goal is to isolate x on one side of the equal sign, and we can do this using inverse operations. For example, the inverse operation of addition is subtraction. Subtract both sides of the equation by 3 to isolate 2x:
2x+3-3=5-3
2x=2
The inverse of multiplication is division. Divide both sides by 2:
2x÷2=2÷2
x=1

Answer:
Let x=number of girls in the class
Then x+27 =total number of students in the class
So our equation to solve is :
40% of (x+27)=x or
0.40(x+27)=x get rid of parens
0.40x+10.8=x subtract 0.40x from each side

Suppose that 2 balls are chosen without replacement from an urn containing 5 white and 8 red balls. Let X1 equal 1 if the 1st ball selected is red, and let it equal 0 otherwise. Let X2 equal 1 if the 2nd ball selected is red, and let it equal 0 otherwise. (i) Give the joint probability mass function of X1 and X2. (ii) Are X1 and X2 independent
Answer:
The probability mass function :
P(X1 = 1, X2 = 1) = 5/13 * 4/12 = 5/39
P(X1 = 1, X2 = 0) = 5/13 * 8/12 = 10/39
P(X1 = 0, X2 = 1) = 8/13 * 5/12 = 10/39
P(X1 = 0, X2 = 0) = 8/13 * 7/12 = 14/39
Step-by-step explanation:
Given :
Number of white balls = 5
Number of red balls = 8
Total number of balls = (5 + 8) = 13
P(X1 = 1, X2 = 1) = 5/13 * 4/12 = (5/13 * 1/3) = 5/39
P(X1 = 1, X2 = 0) = 5/13 * 8/12 = (5/13 * 2/3) =10/39
P(X1 = 0, X2 = 1) = 8/13 * 5/12 = (2/13 * 5/3) =10/39
P(X1 = 0, X2 = 0) = 8/13 * 7/12 =(2/13 * 7/3) = 14/39
