I WILL MARK YOU AS BRAINLIEST IF RIGHT The fastest pitch ever recorded in MLB was thrown by Aroldis Chapman at 5 points 105.1 mph . If the 0.145 kg baseball accelerated 96 m/s / s , how much force did Chapman apply to the ball? Round your answer to the nearest whole number

Answers

Answer 1

Answer: The force was 13.92 Newtons.

Explanation:

First, let's recall the second Newton's law:

The net force is equal to the mass times the acceleration, or:

F = m*a

where:

F = force

m = mass

a = acceleration.

When the player hits the ball with the bat, he applies a force that accelerates the ball for a small period of time, that increases greatly the speed of the ball.

In this case, we know that:

the mass of the ball is 0.145 kg

The acceleration of the ball is 96m/s^2

Then we can input those values in the above equation to find the force.

F = 0.145kg*96m/s^2 = 13.92 N

The force was 13.92 Newtons.

Required:
a. What is the limit of resolution on this microscope?
b. Will you be able to distinguish 2 points that are 300nm apart as being separate, or will they blur into one?

Answers

Answer:

- colony: mass of single-type cells formed from single cell/small chain; pair or small cluster of cells; visible to naked eye

- colony forming unit: not visible to eye, original single cell or small chain/pair or small cluster of cells FROM WHICH colony forms

- Streaking plate: producing isolated colonies upon incubation using streak plate methods in agar

- Quadrant streak: used when sample is of high density

- Zigzag pattern: used when sample is of low density

a. The limit of resolution on this microscope is approximately 1254nm.

b. Two points that are 300nm apart will blur into one and cannot be distinguished as separate using this microscope.

The formula for the limit of resolution (d) is given by:

d = (0.61 × λ) / NA

where λ is the wavelength of light and NA is the numerical aperture.

a. To find the limit of resolution:

Given:

Wavelength of light (λ) = 520nm

Numerical aperture of the low-power objective lens (NA) = 0.25

Substituting these values into the formula, we have:

d = (0.61 × 520) / 0.25

d = 1254nm

Therefore, the limit of resolution on this microscope is approximately 1254nm.

b. To determine if two points 300nm apart can be distinguished:

Given:

Separation between the points (d) = 300nm

Since the separation between the points (300nm) is smaller than the limit of resolution (1254nm), the two points will blur into one and will not be distinguishable as separate entities.

In conclusion:

a. The limit of resolution on this microscope is approximately 1254nm.

b. Two points that are 300nm apart will blur into one and cannot be distinguished as separate using this microscope.

In a football game the running back is running up the field. He starts from rest and runs 4 seconds with an acceleration of 1.3m/s. What is the magnitude of his displacement

Answers

We are given:

initial velocity (u) = 0 m/s

time (t) = 4 seconds

acceleration (a) = 1.3 m/s²

displacement (s) = x m

Solving for the displacement:

from the second equation of motion

s = ut + 1/2 at²

replacing the variables with the given values

x = (0)(4) + 1/2 (1.3)(4)(4)

x = 1/2 * 20.8

Answers

Answer:

19.62 m/s

Explanation:

v = Final velocity

u = Initial velocity = 0

a = g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]

t = Time taken = 2 s

From the equations of linear motion we have

[tex]v=u+at\\\Rightarrow v=0+9.81\times 2\\\Rightarrow v=19.62\ \text{m/s}[/tex]

The speed of the object after 2 seconds is 19.62 m/s

t = 3.5 s

[tex]v=u+at\\\Rightarrow v=0+9.81\times 3.5\\\Rightarrow v=34.335\ \text{m/s}[/tex]

The velocity of the object when it strikes the ground is 34.335 m/s.

[tex]v^2-u^2=2as\\\Rightarrow s=\dfrac{v^2-u^2}{2a}\\\Rightarrow s=\dfrac{34.335-0}{2\times 9.81}\\\Rightarrow s=1.75\ \text{m}[/tex]

An object is pulled with a 85 N force inclined at 27° along a horizontal surface ABC
where AB is smooth but BC is rough.
a) Compute the mass of the object if the object moves with an acceleration of 5
ms-1 along AB.​

Answers

Answer:

m = 15.15 kg

Explanation:

Newton's Second Law of motion states that when an unbalanced force is applied on a body, an acceleration is produced in it in the direction of force. The component of force along the horizontal direction here, will be given by the Newton's Second Law as:

Fx = ma

F Cosθ = ma

where,

F = Magnitude of Force = 85 N

θ = Angle with horizontal = 27°

m = mass of object = ?

a = acceleration of object = 5 m/s²

Therefore,

85 N Cos 27° = m(5 m/s²)

m = 75.73 N/5 m/s²

m = 15.15 kg

Question 8 options:

Diagram A

Answers

Answer:

Diagram A

Explanation:

When an object is travelling in a circular path it has an acceleration called centripetal acceleration, even if it is moving with uniform speed. This acceleration is attributed to the object due to change in the direction of velocity at every instant during the motion.

The direction of the velocity of the object is tangent to the circular path at every instant and if the object beaks free of the circular motion, such as breaking of the string, then it will go in the direction tangent to the circle at that instant. Hence, the diagram that best shows the direction ball will travel is:

A small sculpture made of gold ( rho gold =19320 kg/m^ 3 ) is believed to have a secret central cavity. The weight of the sculpture in air is 11.29 N. When it is submerged in water, the weight is 9.190 N. What is the volume of the secret cavity?​

Answers

Answer:

1.1 x 10⁻⁵m³

Explanation:

Given parameters:

Weight in air  = 11.29N

Weight in water  = 9.190N

Density of gold  = 19320kg/m³

Unknown:

Volume of the secret cavity = ?

Solution:

To solve this problem, we need to find the mass of the secret cavity.

Weight of the cavity  = Weight of sculpture in air  - Weight of sculpture in water

 Weight of cavity  = 11.29N  -  9.190N = 2.1N

 Weight  = mass x acceleration due to gravity

        Mass  =[tex]\frac{2.1}{9.8}[/tex]   = 0.2kg

So;

 Volume of substance can be determined from the density.

 Density  = [tex]\frac{mass}{volume}[/tex]  

   Volume  = [tex]\frac{mass}{density}[/tex]  

 Now insert the parameters and solve;

  Volume  = [tex]\frac{0.2}{19320}[/tex]   = 1.1 x 10⁻⁵m³

A parachutist of total mass 70 kg is falling vertically through the air at a constant speed of 8 m s . What is the total upward force acting on the parachutist

Answers

The parachutist is falling at a constant speed, so the net force acting on them is zero. The only forces acting on the parachutist are their own weight (magnitude w, pointing downward) and the drag produced by the parachute (mag. d, pointing upward). By Newton's second law,

d - w = 0

or d = w. The parachutist's weight is

w = (70 kg) (9.80 m/s²) = 686 N

so that the total upward force is also 686 N.

Tension in the 28.5 degree cable = 72.16 N

Explanation:

Decompose the two tensions T1 (on left cable) and T2(on right cable) in vertical and horizontal components using trigonometric functions sine and cosine. Then balance the forces in the vertical and in the horizontal as shown below:

Horizontal components acting on net horizontal force:

T1 cos(55) =T2 cos(28.5)

then  T1 = T2 (cos(28.5) / cos(55))

Vertical components acting on net vertical force:

T1 sin(55) + T2 sin(28.5) = 125

Now replace T1 with T2 (cos(28.5) / cos(55)) in the last equation:

T2 (cos(28.5) * sin(55)/ cos(55)) + T2 * sin(28.5) = 125

T2 ( cos(28.5) * tan(55) + sin(28.5)) = 125

solving for T2 we get: 72.16 N

now we use this T2 result in the substitution equation:

T1 = T2 (cos(28.5) / cos(55))

T1 = 110.56 N
