Answer:

Since the two vectors form a right angle, no components need to be found for the resultant vector - we already have them!

Vector R's x-component = 3.00 units

Vector R's y-component = 4.00 units

To solve for the magnitude of the displacement, use the distance formula: Square Root of [(3)^2 + (4)^2], which equals 5 units.

To solve for the direction of the displacement, plug in -4 (remember where it was pointing) for y and 3 for x. Tan-1(-4/3) = -53.13°, or 53.13° south of east.Please Mark as Brilliant

The magnitude of vector C is |C| = 3 and It is directed along the negative x - axis.

A vector quantity is a quantity with both magnitude and direction.

Given is vector A is 7.00 units in length and points along the positive x-axis. and vector B is 5.00 units in length and points along the negative x-axis.

Vector A = 7 a[x]

Vector B = - 5 a[x]

Therefore, the given expression to be evaluated is -

C = A + 2B

C = 7 a[x] + 2(- 5 a[x])

C = 7 a[x] - 10 a[x]

C = - 3 a[x]

So, the magnitude of vector C is -

|C| = 3

It is directed along the negative x - axis.

Therefore, the magnitude of vector C is |C| = 3 and It is directed along the negative x - axis.

Answer:

As the temperature increases, the molecules and atoms move faster

Explanation:

Answer:

The first model of the atom was developed by JJ Thomson in 1904, who thought that atoms were composed purely of negatively charged electrons.

This theory was then disproved by Ernest Rutherford and the gold foil experiment in 1911, where Rutherford shot alpha particles at gold foil, and noticed that some went through and some bounced back, implying the existence of a positive nucleus.

In 1926, the Austrian physicist Erwin Schrödinger created a quantum mechanical model of the atom by combining the equations for the behavior of waves with the de Broglie equation to generate a mathematical model for the distribution of electrons in an atom.

Explanation:

The complete question with the scale is missing, so i have attached it.

Answer:

930 g

Explanation:

The block surface is frictionless, therefore, the only force that can possibly be applied to the block from the hamster will be the normal force.

Now, the force of gravity on the hamster acts downward and equals mg. Hence, The normal component will be;

F_n = mgcosθ.

Now, if we Assume that the scale does not respond to horizontal force component, the downward component of the normal force will be expressed as;

F_d = F_n(cosθ)

The scale measures the downward component.

Earlier, we saw that; F_n = mgcosθ

Thus; F_d = mgcosθ × cosθ

F_d = mg(cos²θ)

Now, when the friction was high, the measurement of the scale was;

(m+ M)g

Where ;

m = mass of hamster

M = mass of block

Therefore, when the friction is removed the scale measurement is;

mgcos²θ + Mg or (mcos²θ + M)g

But this is in units of Newton's.

Thus;

Measurement in kg is;

(mcos²θ + M)

We are given;

m = 170 g = 0.17 kg

M = 830 g = 0.83 kg

From the attached scale image,

θ = 40°

Thus;

Measurement = (mcos²θ + M) = ((0.17 cos²40) + 0.83) = 0.93 kg or 930g

Answer:

The mass number of carbon atom is 6+6=12

Answer:6.5 m/s

Explanation:Look at the image I believe that's the answer

The horizontal velocity of the diver would be 6.522 meters / seconds.

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2×a×t²

v² - u² = 2×a×s

As given in the problem, Divers at Acapulco dive from a cliff that is 61 m high. If the rocks below the cliff extend outward for 23 m, then we have to find out  the minimum horizontal velocity a diver must have to clear them,

By using the second equation of motion in the vertical direction,

s = ut + 0.5at²

61 = 0+ 0.5×(-9.81) ×t²

t² = 61/(0.5×9.81)

   = 12.43

t = 3.526 seconds

The horizontal velocity of the diver = 23 meters / 3.526 seconds

                                                            =6.522 meters / seconds

Thus, the horizontal velocity of the diver would be 6.522 meters/second.

Answer:

I believe it is nature vs nurture

Explanation:

The term that represents the debate between genetic and environmental influences on behavior is nature versus nurture. Thus, the correct option for this question is C.

Genetic influences may be defined as the types of concerns that significantly deal with the behavioral and psychological characteristics of an individual which include their intellectual ability, personality, and risk for mental illness with respect to their genetic sequences.

When you talk about the debate between genetic and environmental influences on behavior, the term nature reflects the environmental aspect of the debate while the term nurture reflects the genetic aspects of the debate.

Therefore, nature versus nurture is the term that represents the debate between genetic and environmental influences on behavior. Thus, the correct option for this question is C.

Unknown:

Total distance covered  = ?

Solution:

Speed is a scalar quantity that has magnitude and no direction.

Mathematically;

     Speed  = [tex]\frac{distance}{time}[/tex]

  distance  = speed x time

 Input the parameters and solve for distance;

    Distance  = 25 x 20 = 500m

A person riding a bicycle has the most kinetic energy among the given options, therefore the correct option is C.

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.

The expression for total mechanical energy is as follows

ME= PE+KE

Where ME is the mechanical energy

PE is the total potential energy

KE is the total kinetic energy

The kinetic energy is the body depends on the mass as well as the speed of the object and is given by the mathematical expression as follows

K.E = 1/2*m*v²

Answer:

Equitable education in a healthy democracy includes science and engineering learning for every student. Great science and engineering education engage student so that they develop the knowledge and intellectual dispositions to make sense of the natural and designed worlds.

Explanation:

Answer:

C. They must lose enough of their kinetic energy so that the  attractions between them hold in place as they vibrate.

Explanation:

The "kinetic energy" refers to the energy of an object when it is moving. This is directly proportional to the object's "thermal energy." If the kinetic energy of an object increases, the thermal energy increases and if the kinetic energy decreases, the object's thermal energy decreases as well.

Changing the phase of an object from liquid to solid means that the object will be subjected to low temperature. This means the thermal energy will decrease as well as the kinetic energy. This is known as "freezing." The object needs to lose enough kinetic energy. This results to its particles moving closer together in an attractive force.

So, this explains the answer.
