The magnitude of the force of the bat on the ball is 10000 N
From the question given above, the following data were obtained:
Mass (m) = 0.2 KgInitial velocity (u) = 48 m/sFinal velocity (v) = 52 m/sTime (t) = 2 ms = 2×10¯³ sForce (F) =?The magnitude of the force can be obtained as follow:
F = m(v + u) / t
F = 0.2 (52 + 48) / 2×10¯³
F = (0.2 × 100) / 2×10¯³
F = 20 / 2×10¯³
F = 10000 N
Thus, the magnitude of the force is 10000 N

Jemma purchased six scratch-off lottery tickets and won $25 on the fifth ticket. Which kind of reinforcement schedule does this exemplify? Continuous reinforcement Fixed-ratio reinforcement Variable-ratio reinforcement Fixed-interval reinforcement Variable-interval reinforcement
Answer:
Variable-ratio reinforcement
Explanation:
The kind of reinforcement schedule this exemplifies is variable-ratio reinforcement. The correct option is c.
What is variable-ratio reinforcement?A variable ratio schedule is a reinforcement schedule in which a behavior is reinforced after a random number of responses. This type of schedule produces high, consistent response rates. It is a sort of partial reinforcement in which only a subset of responses are reinforced and no definite pattern exists.
Organisms persevere in reacting in the belief that the next reaction will be the one required to earn reinforcement. A variable-ratio schedule is a partial reinforcement schedule in operant conditioning, in which a response is reinforced after an unknown number of responses.
Therefore, the correct option is c, Variable-ratio reinforcement.

A 40 N box is pushed 5 m up a ramp. The angle of the ramp is 37° above the horizontal. The applied force is parallel to the ramp and opposed by a frictional force of 10.0 N. Find the net increase in potential energy by the crate.
The net increase in potential energy by the crate is negative 49.4 Joules. That is, ΔP.E = - 49.4 J
Given that a 40N box is pushed 5 m up a ramp. The angle of the ramp is 37° above the horizontal.
We can find the height h of the ramp with the equation below;
h = 5sin 37
h = 3.009 m
Mass of the box = 40/9.8 = 4.082 kg
The maximum energy attained = mgh
Maximum Energy = 4.082 x 9.8 x 3.009
E = 120.36 J
The maximum K.E = Maximum P.E
1/2m[tex]U^{2}[/tex] = 120.36
m[tex]U^{2}[/tex] = 240.72
[tex]U^{2}[/tex] = 240.72 / 4.082
[tex]U^{2}[/tex] = 58.97
U = [tex]\sqrt{58.97}[/tex]
U = 7.7 m/s
We can find the acceleration by using third equation of motion
[tex]V^{2}[/tex] = [tex]U^{2}[/tex] - 2aS
Since the box is going to rest, V = 0, and acceleration will be negative
0 = 7.7^2 - 2 x a x 5
10a = 59.29
a = 59.29/10
a = 5.93 m/[tex]s^{2}[/tex]s^2
The applied force F = ma
F = 4.082 x 5.93
F = 24.2 N
Given also that the applied force is parallel to the ramp and opposed by a frictional force of 10.0 N. The net increase in potential energy by the crate will be
ΔP.E = Net work done
ΔP.E = Net force x distance
ΔP.E = (24.2 - 10 - 40sin37) x 5
ΔP.E = - 9.87 x 5
ΔP.E = - 49.4 J
Therefore, The net increase in potential energy by the crate is negative 49.4 Joules.

During an el Niño event warm surface water moves from the western equatorial Pacific Ocean to the eastern equatorial region. Which of the following best describes how the warm water w
affect upwelling off the coast of equatorial South America?
The warm surface water will not change upwelling because this region is at the equator and always has warm water
The warm surface water will increase upwelling because of the difference in salinity between the warm surface water and the cold deep water,
The warm surface water will decrease upwelling because the cooler temperatures on land in the region will prevent upwelling.
The warm surface water will decrease upwelling because of the density difference between the warm surface water and the cold deep water.
The statement 'warm surface water will decrease upwelling because cooler temperatures on land will prevent upwelling' describes how the warm water affects upwelling. El Niño is a climatic phenomenon.
El Niño is a climate phenomenon characterized by the warming of the surface water in the tropical Pacific Ocean.
The upwelling refers to the rising of deeper and colder water to shallower depths (i.e., the movement of deeper water to shallow levels), which occurs during the El Niño phenomenon.
The El Niño occurs every 2 to 7 calendar years as a consequence of the unusual warming of the sea water surface temperatures in the eastern tropical Pacific Ocean.

In ΔABC, ∠B is a right angle, AB = 30, and sec A = 5/3. Find the value of csc C in fraction and in decimal form.
I will mark brainliest if you are correct!
sec(A) = 5/3 ⇒ cos(A) = 3/5
Angles A and C are complimentary (they sum to 90°), so
sin(C) = cos(A) = 3/5
since sin(90° - x) = cos(x) for all x, and in turn
csc(C) = 1/sin(C) = 5/3

which factor contributes least to the rate at which a stream deposits sediment?
Solution
To determine the angle of the velocity, we use the following equation.
Tan θ = Vertical velocity ÷ Horizontal velocity
As the particle moves from its initial position to its final position, its vertical velocity decreases at the rate of 9.8 m/s each second. During this time its horizontal velocity is constant. To determine the time when the angle is 45˚, we need to determine the object’s vertical velocity at this angle. Let’s determine the vertical and horizontal components of its initial velocity.
Vertical = 50 × sin 60˚, Horizontal = 50 × cos 60˚ = 25 m/s
Since horizontal velocity is constant, let’s put 25 m/s and 45˚ into the tangent equation.
Tan 45 = Vertical velocity ÷ 25
Vertical velocity = 25 m/s
To determine the time for the vertical velocity to decrease from its initial value to 25 m/s, use the following equation.
vf = vi – a × t
a = 9.8
25 = 50 × sin 60˚ – 9.8 × t
t = (25 – 50 × sin 60˚) ÷ -9.8
This is approximately 1.83 seconds.

What is the percent rate of increase for the exponential function f (x) = 2.5(1.3)^x
Answer:
f(x) = d/ dx (2.5x1.3)
f(x) =2.5×d/dx(1.3*)
f(x) =5xIn 13/10 x 13*/2×10*
So the answer is
f(x)=5•IN13/10•13*/2•10*
That's the correct answer I see in my book
f(x)=5•IN13/10•13*/2•10* is the percent rate of increase for the exponential function.
What is an exponential function?The formula for an exponential function is f (x) = ax, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.
Y=abx y = a b x is the fundamental exponential function equation, where a denotes the y-intercept and b the growth factor.
When b > 0 and b 1, an exponential function has the form f(x) = bx. The base is b, and the exponent is x, just like in any exponential expression. The development of bacteria is an illustration of an exponential function. Some germs multiply by two per hour.
f(x) = d/ dx (2.5x1.3)
f(x) =2.5×d/dx(1.3*)
f(x) =5xIn 13/10 x 13*/2×10*

Explanation:
GPS data is extensively used in the study of certain animals to understand their movements, behaviors, and habitats.
Researchers attach GPS tracking devices to animals such as migratory birds, marine mammals, and large terrestrial mammals. These devices record the animal's location at regular intervals, allowing scientists to track their movements over time.
By analyzing GPS data, researchers can identify migration routes, feeding areas, and breeding grounds of the studied species.
This information is vital for conservation efforts, as it helps identify critical habitats and migration corridors, assess the impact of human activities, and inform effective management strategies to protect these animals and their ecosystems.
GPS technology revolutionized the understanding of animal behavior and contributed significantly to wildlife conservation efforts.
