As a result, the provided sphere's intersection with the yz-plane would be (y-2)²+(z-5)²=7.

When two streets or lines cross, it is known as an intersection. The two places where crossings are most likely to occur are in math class and in traffic. An intersection in mathematics is the place where two lines converge. This is the common theme among the lines.

Equation (x+3)²+(y-2)²+(z-5)²=16

Intersection (y-2)²+(z-5)²=7

We are asked to write an equation of the sphere with center (-3,2,5) and radius 4.

We know that equation of a sphere with radius 'r' and center (h,k,l) at is in form:

(x-h)²+(y-k)²+(z-l)²=r²

Since center of the given sphere is at point (-3,2,5) , so we will substitute h=-3,k=2 ,l=5 and r=4 in above equation as:

(x-(-3))²+(y-2)²+(z-5)²=4²

(x+3)²+(y-2)²+(z-5)²=16

Therefore, our required equation would be (x+3)²+(y-2)²+(z-5)²=16

To find the intersection of our sphere with the yz-plane, we will substitute x=0 in our equation as

(0+3)²+(y-2)²+(z-5)²=16

9+(y-2)²+(z-5)²=16

9-9+(y-2)²+(z-5)²=16-9

(y-2)²+(z-5)²=7

As a result, the provided sphere's intersection with the yz-plane would be:

It takes 16.5 seconds to reach its top speed of 80.0 km/h, starting from rest.

A branch of physics called kinematics, which was evolved from classical mechanics, defines how points, bodies, and systems of bodies (groups of objects) move without taking into account the forces that propel them. The discipline of kinematics is sometimes thought of as a subfield of mathematics and is frequently referred to as the "geometry of motion." Any known values of the location, velocity, and/or acceleration of points inside the system are declared as initial conditions for a kinematics issue, together with the geometry of the system. The position, velocity, and acceleration of any unidentified system components can then be calculated using geometrical considerations.

Where [tex]v[/tex] is the final velocity and [tex]v_{0}[/tex] is the initial velocity, we utilize the formula [tex]v = v_{0}+at[/tex] (because the train starts from rest), [tex]a= 1.35\frac{m}{s^{2} }[/tex], [tex]v_{0} = 80.0\frac{km}{h} = 22.22\frac{m}{s}[/tex]

The change in velocity is 2m/s

Given ,

mass of baseball m = 0.5kg

force on baseball F = 10 N

Duration .i.e. time t = 0.1s

To find here change in velocity =?

Solution,

The impulse(J) of an object is equal to,

J = F× T

Where J is the impulse of the baseball and F is force on baseball at time t.

The impulse is equal to the change in momentum of the baseball and its unit is (N.s) Newton -second. it is a vector quantity therefore the dimension is [LMT⁻¹]. Then the impulse j is given as ,

J = m(v-u)

Here J is impulse ,m is mass, (v-u) is change in velocity .From equating the both impulse equations then can be write as,

m(v-u) = F× t

(v -u) =( F × t)/m

(v -u) = (10N× 0.1 s)/0.5k

(v -u) = 2m/s

Hence the change in velocity (v -u) of baseball is 2m/s.

It will cost $68 to travel 975 kilometers for an automobile if the cost of gasoline is $2.75 per gallon.

This simple calculation can be explained as below calculation of the cost of driving such a distance is done by conversion of the distance into miles and multiplying such distance by $2.75.

First calculate the kilometers to miles.

975 kilometers is converted as 605.837 miles. Now the division of mileage of automobile will be calculated as,

Gasoline required = Distance travelled/ mileage

=605.837/24.5

=24.72 gallons of gasoline required.

Now we have to calculate the cost of gasoline.

Gasoline cost= gallons x cost per gallon

= 24.72 x 2.75

=$68

So, it is calculated that the cost of gasoline/ cost of driving is $68.0.

Hence, it would cost $68 to travel 975 kilometers for an automobile when the cost of gasoline is $2.75 per gallon.

The two principal factors that affect the force of air resistance on a falling object are speed  and  cross-sectional area of the object.

When an object falls through the air, it mostly encounters some sort of resistance to its speed and this resistance is known as air resistance.

This resistance is present because of the collisions of the air molecules with the frontal surface molecules of the object.

As the speed is increased of the object so that increased amount of air resistance. speed of the object is directly proportional to the air resistance.

The cross-section of solid is defined as the shape obtained by the intersection of solid by a plane .

The rate of change of distance with respect to time is known as speed.
