The minimum speed object must have at the top of the loop is 3.8m/s.

Friction is the force that resists the motion of an object, it works in the opposite direction of applied force. Centripetal force is the force applied to the center of the body moving in a circular motion, whereas gravitational force is the pull of gravity on a body i.e., it attracts a body toward the ground.

Diameter of loop= 3m

thus radius = 1.5m

Centripetal force =< gravitational attraction the object has.

Centripetal force ,F=mv^2/r ----1

where  M= mass v= velocity and r= radius

gravitational force is F=ma -----2

let 1=2

mv^2/r=ma

m is common so can be canceled out

a=v^2/r

for v= 9.8m/s^2

a= 9.8^2/1.5

a=3.834057903

Therefore, the minimum speed object must have at the top of the loop is 3.834m/s.

Jee's trip from New York to Boston would take approximately time 4.5 hours.

To calculate the time it would take Jee to travel from New York to Boston, we need to divide the total distance (approximately 280 miles) by the average speed (42 mph). This gives us a total time of 6.67 hours. We then need to subtract the time it took Jee to travel from Boston to New York (6 hours) to get the total time for the return trip. 6.67 hours - 6 hours = 4.5 hours. Therefore, Jee's trip from New York to Boston takes approximately time 4.5 hours. Jee's trip from New York to Boston would take approximately 4.5 hours.

value of p = 7 and value of q = 10.

The word consecutive implies an unbroken sequence that means terms approaches forward by following a specific order. Within a consecutive sequence the gap between each term is the same.

given, 4, p, q, 13 are consecutive terms, find the value of P and Q.

As the above four are consecutive number so starting from the 4 we write the list in an unbroken sequence.

At first difference between highest and lowest number = 13- 4 = 9

now this difference is divided by the number of gaps between the sequence, we find there are 3 gaps between four numbers.

order of sequence = 9/ 3 = 3

now the next number after 4 will be 4+3 = 7

in the next, 7+3 =10

finally, we get 10+3 =13

so, the consecutive numbers are 4, 7, 10, 13.

A two-dimensional (2D) coordinate system is a system used to define the position of points in a two-dimensional plane.

A 2D coordinate system can also be used to represent other kinds of data, such as temperature, elevation, or pressure. In this case, the two coordinates are usually called the x-axis and y-axis, and they are both used to measure the same physical quantity.

It is most commonly used in mathematics and engineering to plot graphical data such as graphs, charts, and diagrams. In a 2D coordinate system, each point is represented by two numbers, called coordinates, which indicate the position of the point in relation to a fixed reference point, called the origin. These coordinates usually describe the horizontal (x) and vertical (y) distances between the point and the origin. The set of all points in the 2D coordinate system is called the coordinate plane.

Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, A line passes through the point (-6, 5) and has a slope of 1/2.

An ordered pair is a set of two values, (x,y), where x and y are the coordinates. In an ordered pair, the first element is typically referred to as the x-coordinate, or the "first component" and it represents the horizontal position of the point on a coordinate plane. The second element is typically referred to as the y-coordinate, or the "second component" and it represents the vertical position of the point on a coordinate plane.

So, to find the first and second element of a pair, you can refer to the first element as the x-coordinate or the first component and the second element as the y-coordinate or the second component.

For example, in the ordered pair (4,3), the first element is 4, which represents the x-coordinate, and the second element is 3, which represents the y-coordinate.

The amount that they will have saved after 2 weeks is $1,737.

Tom, you can refer to a quantity or number of something using the word "amount." It is typically used to refer to an amount of money, like when people discuss their income, but it can also be used to describe a quantity of something, such as the volume of water in a tank or the time required to complete a task.

We must divide the difference between Ezra and Haley's initial deposits by the difference between their weekly installments to figure out how many weeks it will take them to save the same amount of money. In this instance, their initial deposits differed by $804 ($862 - $58), while their weekly installments differed by $402 ($71 - $473). We can calculate that it will take them two weeks to save the same amount of money by dividing $804 by $402.

After two weeks, they will have $1,737 in savings. Haley will have $1,737 ($862 + $71 + $71 + $703) and Ezra will have $1,737 ($58 + $473 + $473 + $733) in their accounts after two weeks.

He wants to have at least $15 left over after buying t-shirts, so he can buy up to $73-15 = $58 worth of t-shirts. Each t-shirt costs $5, so he can buy a maximum of 11 t-shirts (58/5=11.6) with no remainder. So Tyrone can buy 11 t-shirts and he will have $73-11*5 = $18 left.
