Answer:

A- 125 N

Explanation:

Given parameters:

Force applied to the mass  = 40N

Acceleration = 8m/s²

First let us find the mass of this body before we proceed to solve the main problem.

  From Newton's second law of motion:

         Force  = mass x acceleration

          40  = mass x 8  

           mass  = 5kg

New acceleration  = 25m/s²

 The force needed;

           Force  = mass x acceleration

          Force  = 5 x 25  = 125N

Answer:

The magnitude and direction of the force applied by Steinberg are approximately 15.192 newtons and 126.704º.

Explanation:

The chew toy is at equilibrium and experimenting three forces from three distinct dogs. The Free Body Diagram depicting the system is attached below. By Newton's Laws we construct the following equations of equilibrium: (Sp is for Spot, F is for Fido and St is for Steinberg) All forces and angles are measured in newtons and sexagesimal degrees, respectively:

[tex]\Sigma F_{x} = F_{F}\cdot \cos \theta_{F} + F_{St,x} = 0[/tex] (1)

[tex]\Sigma F_{y} = F_{F}\cdot \sin \theta_{F}-F_{Sp}+F_{St,y} = 0[/tex] (2)

If we know that [tex]F_{F} = 20\,N[/tex], [tex]F_{Sp} = 30\,N[/tex] and [tex]\theta_{F} = 63^{\circ}[/tex], then the components of the force done by Steinberg on the chewing toy is:

[tex]F_{St,x} = -F_{F}\cdot \cos \theta_{F}[/tex]

[tex]F_{St,x} = -(20\,N)\cdot \cos 63^{\circ}[/tex]

[tex]F_{St, x} = -9.080\,N[/tex]

[tex]F_{St,y} = F_{Sp}-F_{F}\cdot \sin \theta_{F}[/tex]

[tex]F_{St,y} = 30\,N-(20\,N)\cdot \sin 63^{\circ}[/tex]

[tex]F_{St, y} = 12.180\,N[/tex]

The magnitud of the force is determined by Pythagorean Theorem:

[tex]F_{St} = \sqrt{F_{St,x}^{2}+F_{St,y}^{2}}[/tex]

[tex]F_{St} =\sqrt{(-9.080\,N)^{2}+(12.180\,N)^{2}}[/tex]

[tex]F_{St} \approx 15.192\,N[/tex]

Since the direction of this force is in the 3rd Quadrant on Cartesian plane, we determine the direction of the force with respect to the eastern semiaxis:

[tex]\theta_{St} = 180^{\circ} + \tan^{-1} \left(\frac{F_{St,y}}{F_{St,x}}\right)[/tex]

[tex]\theta_{St} = 180^{\circ} + \tan^{-1} \left(\frac{12.180\,N}{-9.080\,N}\right)[/tex]

[tex]\theta_{St} \approx 126.704^{\circ}[/tex]

The magnitude and direction of the force applied by Steinberg are approximately 15.192 newtons and 126.704º.

Answer:

640N

Explanation:

Mass of a metal bar, m = 65 kg

We need to find the normal force exerted by the ground on the bar.

The normal force on an object acts in upward direction. The magnitude of normal force is equal to its weight.

N= mg

Put m = 65 kg and g = 9.8 m/s²

N = 65 × 9.8

= 637 N

or

N = 640 N

Hence, the normal force is 640 N.

Answer:

Explanation:

Answer:

Described below

Explanation:

- The behaviorist theories: This theory is of the claim that language is learned through the means of reinforcement and imitation. This means that little children can mimic the language of individuals around them and also receive reinforcement to correct the formation of their words. Thereafter, words not reinforced will eventually no longer be in use.

- The nativist theories: This theory is of the claim that individuals possess an innate process which is used in language learning and is widely known as "language acquisition device" (LAD). This device is used to assist in helping them automatically learn languages.

-The interactionist theories: This theory is of the claim that innate processes which is also referred to as genetic predispositions and learning experiences from the environment both help in language development.

The behaviorist theory posits that infants learn oral language through imitation, rewards, and practice.

It should be noted that human role models in an infant's environment provide the stimuli and rewards.

Nativist theories state that language is an innate fundamental part of the human genetic make-up and it is a natural part of the human experience. Children have language-specific abilities that assist them as they work towards mastering a language.

The interactionist theories states that innate processes help in language development. It states that children can only learn language from the people who want to communicate with them.

Explanation:

Answer:

C)No

Explanation:

When moving oxidation numbers down as subscripts in an ionic bond, you do not include the charge either positive or negative.

The process of moving oxidation number down as subscript is known as exchange of valency.

The combining power is used in exchanging valency and this is oxidation number exchanged. The number corresponds to the number of electrons usually lost or gained or shared by atoms of elements during chemical combination or the number of positive or negative charges carried by ions.

The combining power is exchanged as simple whole number ratio during the formation of chemical formulae of compounds.

Explanation:

key to this problem is the impulse-momentum theorem which states that the change in the momentum of an object is equal to the impulse applied into it.

J

=

Δ

p

,

where

J

is the impulse and

Δ

p

is the change in momentum. Basically, the impulse is the product of force and time duration, that is,

J

=

F

Δ

t

In this problem, the impulse would be the product of the force stopping the rock and

0.7

s

.

On the other hand, momentum

p

is the product of the mass

m

and velocity

v

. Therefore, the change in momentum is given by

Δ

p

=

then

Therefore, using the correct significant figures (in this case, we need one significant figure since 2 kg, 6 m/s and 0.7 s all have one) in the final answer, we would need to have approximately

Answer:

Explanation:

Given parameters:

Acceleration = 0.0m/w

Initial velocity = 0m/s

Final velocity  = 00m/s

Unknown:

Distance traveled  = ?

Solution:

To solve this problem, we use the expression below:

    q0   = y   + 0w

W is the final velocity

Y is the initial velocity

C is the acceleration

P is the distance

          0²  = 0²   +  (0 x 0.0 x S)

          000  = 00.0S

            S = 0m

Answer:

as it travel through the space it behave like a wave and has an oscillating electric field components and an oscillating magnetic field

Electromagnetic waves are created by a charged particle that generates an electric field. The electric field creates a magnetic field. As the charged particle moves, the electric field and magnetic field keep changing, which causes the wave to move.

Answer:

d = 27.03 m

Explanation:

Constant Speed Motion

An object travels at constant speed if the ratio of the distance traveled by the time taken is constant.

Expressed in a simple equation, we have:

[tex]\displaystyle v=\frac{d}{t}[/tex]

Where  

v = Speed of the object

d = Distance traveled

t = Time taken to travel d.

From the equation above, we can solve for d:

d = v . t

It's required to find the distance traveled by someone walking at v=1.7 m/s for t=15.9 s. Substituting in the last equation:

d = 1.7 m/s * 15.9 s

d = 27.03 m
