The horizontal component of the boat's velocity is 40.96 m/s.

The horizontal component of the boat's velocity is the velocity of the boat along the horizontal direction or x - axis of the boat's motion.

The magnitude of the horizontal component of the boat's velocity is calculated as follows;

Vx = V cos (θ)

where;

Vx = 50 m/s  x  cos (35)

Vx = 40.96 m/s

Thus, the horizontal component of the boat's velocity is a function of the initial velocity and the direction of the velocity.

To make a proper 2 perfect solution, a solvent should be added but the general method for making a 2 perfent solution is to have 2 grams of solvent dissolved in 98-100 ml of water.

A solution is a mixture in which small parts are divided into a large part. A solute is a substance that dissolves in a substance. A solute is in a completely liquid or gaseous state where the solute dissolves to form a solution.

Percentage of mass can be  calculated by dividing the mass of the component with the total mass of the mixture, multiplied by 100 which is given as follows:

[tex]\frac{2 g}{100 g_{\text {mass of solute }+\text { mass of solvent }}} \times 100[/tex]

A perfect solution is a solution that contains the maximum amount of solute that can be dissolved in the solution. On the other hand, an unsaturated solution is a solution in which the amount of other solutes dissolved in the solute is less than the value of the solubility index.

Like molality, percentage is also a way to describe the solution ratio. The percentage is calculated by dividing the amount of the material with the total amount, and the result is multiplied by 100. Normality is also a way to determine the balance of the solution.

Option a; Correlational designs causal effects between variables, researchers must use.

Correlational research's objectives are to identify relationships between variables and to make it possible to predict the future based on the past. It's possible that one of two variables is a cause and the other is an effect if there is a correlation between them. But due to the correlational research methodology, it is impossible to distinguish between the two. To be safe, researchers avoid deriving causal inferences from Correlational designs. Correlational study involves monitoring two variables and looking at how they relate to one another without changing an independent variable. Correlation may not imply causation.

An example of negative reinforcement is removing an unpleasant stimulus in order to increase a desired behavior. For example, if a child is misbehaving in class and the teacher takes away their phone as a consequence, the child is more likely to stop misbehaving in order to get their phone back.

Negative reinforcement is a behavior modification technique in which an unpleasant stimulus is removed in order to increase a desired behavior. It is one of the four quadrants of operant conditioning, along with positive reinforcement, punishment, and extinction. An example of negative reinforcement is taking away a child's phone if they are misbehaving in class. By removing the phone, the child is more likely to stop misbehaving in order to get the phone back. It can also be used for animals, such as a dog that is barking too much. The owner can take away its food bowl if it continues to bark and the dog will be more likely to stop barking in order to get its food bowl back. Negative reinforcement is used to increase the desired behavior, but it is important to ensure that the unpleasant stimuli are removed in a humane way.

Answer:

Wavelength = c/f

Frequency = c/wavelength

Energy = mass * [tex]c^2[/tex] [[tex]e = mc^2[/tex]]

Explanation:

c is the speed of light constant -> [tex]3 * 10^8[/tex]

f is the frequency of the wave

Answer:

a + b = c      where a and b and c are vector quantities

Since c is the result of adding vector b to vector a (to add two vectors the vectors are connected head to tail)

a^2 + b^2 - 2 ab cos θ = c^2 is an expression of such a relationship

Note that a^2 + b^2 = c^2 if a and b are at right angles to one another

Another way to express this is:

a x + b x = c x    where a and b are the x-components of a and b

a y + b y = c y      describes the y -components of a and b

The above two equations will provide the x and y components of vector c

The wavelength of a wave is the distance or length between its two subsequent crests or troughs.

A wave's wavelength gives information about its length. The wavelength is the distance between the "crest" (top) of one wave and the crest of the following wave.

The distance of point where gravitational acceleration a due to earth is 1/10 of its value from surface is  7436.8km.

We know that value of acceleration due to gravity at surface of earth is given by the formula g=GM/r²

where G is the earth's gravitational constant, M is the mass of earth and r is the distance between center and surface of earth.

Now,when we consider a point outside the surface of earth as h then value of acceleration due to gravity is =GM / (r+h)²

Now,we are given that value of acceleration due to gravity is 1/10 to the value at surface

∴GM / (r+h)²=(1/10) × (GM/r²)

=>r²/(r+h)² = 1/10

=>r/(r+h)=  √(1/10)

=>r/(r+h)= 1/√10

On further solving,we get

=>√10 ×r=r+h

=>r×(√10-1)=h

Since this point is from center of earth and we need to find point from surface,there distance of point is =h-r=r×(√10-1)-r=r×(√10-2)=1.162r

Now,we know that radius of earth is 6400km

So,on putting =1.162r=1.162×6400=7436.8Km

Hence,distance of point from surface of earth is 7436.8km.

The speed of a body falling freely from rest at time t seconds is given by the formula v = gt + v0, where g is the acceleration due to gravity (in this case, -10 m/s) and v0 is the initial velocity (in this case, 0 m/s). To find the speed after falling 80 m, we need to find the time t that corresponds to this displacement. We can use the formula for displacement to find t: d = -1/2 gt^2 + vt + d0. Plugging in the values and setting d = -80 m, we get -80 m = -1/2 (-10 m/s) t^2 + 0 m/s t + 0 m. Solving for t, we get t = 2 s. Plugging this value of t back into the formula for speed, we get v = (-10 m/s) (2 s) + 0 m/s = -20 m/s.

In this case, the initial velocity is -20 m/s and the time elapsed is 1 s. The final velocity is not given, so we cannot use this formula to find the acceleration.

6. The displacement of an object with constant acceleration is given by the formula d = 1/2 at^2 + vt + d0, where a is the acceleration, v is the initial velocity, t is the time elapsed, and d0 is the initial displacement. In this case, the acceleration is -10 m/s^2, the initial velocity is -20 m/s, the time elapsed is 4 s.

Speed is a measure of how fast an object is moving. It is defined as the distance an object travels per unit of time.

The automobile, which weighs 388 newtons, is at the bottom of the depression. At 17.15 m/s, the automobile loses contact with the bumpy road.

The normal force is the force that surfaces use to prevent solid objects from piercing one another. Normal forces include contact forces. Two surfaces that are not in contact cannot be moved by a normal force.

r = 30 m

v = 10 m/s

m = 60 kg

At the bump

N = mg - mv^2 / r

N = 60 x 9.8 - 60 x 10 x 10 / 30 = 588 - 200 = 388 newton

So, mg = mv^2 / r

v^2 = r x g = 30 x 9.8 = 294

Explanation: v = 40 m/s, H = 10m, g = 9.8 m/s2

H = (v * sinθ)^2 / 2g

H = v^2 * (sinθ)^2 / 2g

H = (40)^2 * (sinθ)^2 / 2g

H = 1600 *  (sinθ)^2 / 2g

Cross multiply

2gH = 1600 * (sinθ)^2

2 * 9.8 * 10 = 1600 * (sinθ)^2

196 = 1600 * (sinθ)^2

Make (sinθ)^2 the subject of the formula

(sinθ)^2 = 196 / 1600

Take the square root of both sides
