from the top of a vertical tower 248 m high , a stone is projected vertically downwards with a speed of 8 ms . After x seconds another stone is projected vertically upwards from the level of the base of the tower with a speed 25 ms . Given that two stones are at same height moving in the same direction 6 seconds after projection of the first stone , calculate :
1) value of x
2) the velocity of the second stone at this instant
The value of x, which is the time delay between the two stones' projections, is 1.4 seconds. The velocity of the second stone 6 seconds after the first stone's projection (so 1.4 seconds after its own projection) is 11.32 m/s.
Explanation:This question involves physics concepts, particularly with motion under gravity, velocity, and displacement. We need to use these principles of Physics to solve the problem.
First, let's calculate the displacement of the first stone 6 seconds after it is thrown. Since the stone is thrown downwards, its final displacement (S1) is given by the equation of motion:
S1 = ut + 0.5gt2, where u is initial velocity (8 m/s), g is acceleration due to gravity (9.8 m/s2), and t is the time (6 seconds).
Therefore, S1 = 8*6 + (1/2)*9.8*6*6 = 48 + 176.4 = 224.4 m.
The first stone is thrown from a tower of height 248 m, so its displacement from the base of the tower is
248 - S1 = 248 - 224.4 = 23.6 m.
The second stone is thrown upwards from the base of the tower, Therefore, after t=x seconds, it travels upward by S2 = ut - 0.5gt2 (=25x - 0.5*9.8*x2).
At t=6 seconds, it must be at a the same height as the first stone (23.6 m). So we set 25x - 0.5*9.8*x2 = 23.6, and solve this quadratic equation to find x = 1.4 seconds.
The second part of the question asks for the velocity of the second stone at this instant. The velocity of an object thrown upward-moving object is given by
v = u - gt, here u = initial velocity = 25 m/s, g = 9.8 m/s2 and t=x=1.4 seconds. Plugging in these values, we find that v = 25 - 9.8*1.4 = 11.32 m/s.

Alan drove 756 miles in 12 hours. at the same rate, how many miles would he drive in 8 hours?
Alan would drive 504 miles in 8 hours.
Explanation:To find out how many miles Alan would drive in 8 hours, we can set up a proportion using the information given. Since Alan drove 756 miles in 12 hours, we can write the proportion as:
12 hours / 756 miles = 8 hours / x miles.
To solve for x, we can cross-multiply and then divide:
12 * x = 8 * 756
x = (8 * 756) / 12
x = 504
Therefore, Alan would drive 504 miles in 8 hours.

the current value of a baseball card is 80 times its original value the baseball card is worth $36 write and solve an equation to find the original value of the baseball card
To find the original value of a baseball card that is now worth 80 times its original value, you divide the current value of $36 by 80, resulting in an original value of $0.45.
Explanation:The student wants to find the original value of a baseball card that is currently worth 80 times its original value and has a present worth of $36. We set up the equation: original value multiplied by 80 equals current value (80 × original value = $36). To find the original value, we divide the current value by 80.
Write the equation: 80 × original value = $36.Divide both sides of the equation by 80 to isolate the original value. So, original value = $36 ÷ 80.Calculate the result: original value = $0.45.The original value of the baseball card was $0.45.

What can you infer about elements that are in the same group?
a. they will have the same atomic mass
b. they will display similar chemical and physical properties
c. they will contain the same number of protons
d. they will emit x rays of similar frequency
Answer:
b.They will display similar chemical and physical properties.
Step-by-step explanation:
We have to find about the elements that are in the same group.
In modern periodic table
Elements are arranged in group according to similar properties.
The elements which have same properties are placed in the same group and mass of different elements are different in the group.
The outer electronic configuration of every element in the same group are same.
Therefore, the physical and chemical properties of the elements are same in the group.
Hence, option B is true.
Answer:b.They will display similar chemical and physical properties.

[tex]4x+y>-6[/tex]
[tex]4(2)+0>-6[/tex]
[tex]8>-6[/tex] True

(0, −9) , plug in 0 for x and -9 for y
[tex]4x+y>-6[/tex]
[tex]4(0)-9>-6[/tex]
[tex]-9>-6[/tex] False
(-1, −1) , plug in -1 for x and -1 for y
[tex]4x+y>-6[/tex]
[tex]4(-1)-1>-6[/tex]
[tex]-5>-6[/tex] True
Final answer:
The ordered pairs that are solutions to the inequality 4x+y>-6 are (2, 0), (4, -20), and (-1, -1) as they satisfy the condition when substituted into the inequality.
Explanation:
To determine which ordered pairs are solutions to the inequality 4x+y>-6, we need to plug the x and y values from each ordered pair into the inequality.
For the pair (2, 0), we substitute x = 2 and y = 0 into the inequality: 4(2) + 0 > -6, which simplifies to 8 > -6. This is true, so (2, 0) is a solution.For the pair (-3, 6), we substitute x = -3 and y = 6: 4(-3) + 6 > -6, which simplifies to -12 + 6 > -6. This gives -6 > -6, which is not true, so (-3, 6) is not a solution.For the pair (4, -20), we substitute x = 4 and y = -20: 4(4) - 20 > -6, which simplifies to 16 - 20 > -6. This gives -4 > -6, which is true, so (4, -20) is a solution.For the pair (0, -9), we substitute x = 0 and y = -9: 4(0) - 9 > -6, which simplifies to -9 > -6. This is not true, so (0, -9) is not a solution.For the pair (-1, -1), we substitute x = -1 and y = -1: 4(-1) - 1 > -6, which simplifies to -4 - 1 > -6. This gives -5 > -6, which is true, so (-1, -1) is a solution.The correct solutions to the inequality are the ordered pairs (2, 0), (4, -20), and (-1, -1).

What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
⇒ 15 - 35/7 - 2 + 3 - 4
⇒ 15 - (35/7) -2 + 3 - 4
Apply the division operation,
⇒ 15 - 5 - 2 + 3 - 4
Rearrange the terms in the above equation
⇒ 15 + 3 - 5 - 2 - 4
⇒ 18 - 11
Apply the subtraction operation,
⇒ 7
⇒ 10 + 2 (9-5) - 16/18
⇒ 10 + 2(4) - 8/9
⇒ 10+8 - 8/9
Apply the addition operation,

An art student wants to make a model of the classroom. The length of the classroom is 2.4 times its width. The length of the student's model is 42 in. What should the width of the model be?
Answer:
Width of the model is:
17.5 in
Step-by-step explanation:
The length of the classroom is 2.4 times its width.
Length=2.4×width
The length of the student's model is 42 in.
Let w be the width of student's model.
By using the equation Length=2.4×width , we get
42=2.4×w
⇒ [tex]w=\dfrac{42}{2.4}[/tex]
⇒ w=17.5
