Question 5
The head of a hammer is often made of steel. This makes the head heavy, which helps create a strong force for driving nails. Steel is also strong. The
head of a hammer must be strong to resist what force?

Answers

Answer 1

Answer:

the nails

Explanation:

Answer 2

The force of the nail pushing in the opposite direction. The correct option is option D among all the given options.

What is force?

A force in physics is an effect that changes the velocity of a mass-moving object, causing it to accelerate from rest, for example. It is a vector quantity since it can be a push or even a pull and always has magnitude and direction.

The head of a hammer is often made of steel. This makes the head heavy, which helps create a strong force for driving nails. Steel is also strong. The head of a hammer must be strong to resist the force of the nail pushing in the opposite direction.

Therefore,  the force of the nail pushing in the opposite direction. The correct option is option D.

A bullet is fired at an angle of 45°. Neglecting air resistance, what is the direction of acceleration during the flight of the bullet?
a) upward
b) downward
c) dependent on the initial velocity
d) at a 45 angle​

Answers

Answer:

b) downward. Correct choice

Explanation:

Projectile Motion

It's known as the type of motion that experiences an object that is projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.

The gravity manifests through the acceleration of gravity g whose value is [tex]9.8 m/s^2[/tex] and points downward. The object will eventually fall to the ground at a time and speed which depends on the initial speed and launch angle.

When the bullet is fired regardless of the initial speed and angle, the only acceleration of the system is g, thus:

b) downward. Correct choice

The acceleration acts on the bullet will be the acceleration due to gravity that is g and has a downward direction.

What will be the direction of the acceleration of Bullet fired?

Since the bullet is fired at an angle of 45 so the bullet will travel in a projectile. So every point in time the acceleration due to gravity will act on the bullet.

After some point in time, the bullet will come to the surface of the earth as the energy in the bullet will reduce.

As we know that anything present on the earth is under the influence of the earth's gravity.

So the fired bullet will experience acceleration due to the gravity of the earth and the direction of the acceleration will always be downwards.

So the bullet will eventually fall to the ground at a time and speed which depends on the initial speed and launch angle.

Thus the acceleration acts on the bullet will be the acceleration due to gravity that is g and has a downward direction.

Using our knowledge of physics... If we know that the moving man travels 10 meters, has an initial velocity of 0 m/s and an acceleration of 1 m/s, use the equation d = vi t + 1/2 a t^2 to solve for time.

Answers

Answer:

t= 4.5s

Explanation:

vi=0m/s

a= 1m/s

d=10m

10m= 0(t) + 1/2(1m/s)(t^2).    0xt cancels out, 1/2 of 1= .5

10m=  .5m/s(t^2)   Divide both sides by .5

20m= t^2.  Take square root of each side

Square root of 20 is 4.472135954999579

sig figs, t= 4.5 s

T=4.5s is the correct answer I think

What collides and creates a movement of heat called conduction?

A. photons

B. compounds

C. Molecules

D. atoms

Answers

Answer:

c.

Explanation:

Molecules collide and create a movement of heat called conduction.

What is conduction?

Conduction is defined as a process  as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to  a body which is cold.

In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules  while in liquids and gases it is due to the random motion of the molecules ,

When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state  conduction 2) transient conduction.According to the type of energy conduction is of three types:

1) heat conduction

2) electrical conduction

3)sound conduction

A person jogs 4.0 km in 32 minutes, then 2.0 km in 22 minutes, and finally 1.0 km in 16 minutes. What is the jogger's average speed in km per minute?​

Answers

Answer:

0.0928km/min (4dp)

Explanation:

To find the jogger's speed in km per minute, we just need to divide the number of km jogged by the time in minutes it took to jog that distance. This will give us the distance they jogged every minute which is their speed.

4km in 32 minutes:

4/32 = 0.125km/min

2km in 22 minutes:

2/22 = 0.091 (3dp)km/min

1km in 16 minutes:

0.0625km/min

Now to find the average speed of these 3 speeds, we just add them all together and divide by how many values there are (3 values).

Average (mean)  = [tex]\frac{0.125+0.091+0.0625}{3}[/tex]

Average = 0.2785/3

Average speed of jogger = 0.0928 (4dp) km/min

An object launched at 65 degrees from the horizontal would have the same range
(distance travelled) as an object launched from? Write only the WHOLE number with
no units (example: 65)

Answers

Answer:

An object launched from 65° will have the same range as an object launched from 25°

Explanation:

The formula for the horizontal range, R, is given as follows;

[tex]R = \dfrac{v \times sin(2\cdot \theta)}{g}[/tex]

Therefore, given that sinθ increases from 0 to 1 for θ values from 0 to 90° and decreases from 1 to 0 for θ values from 90° to 180°, and that the values of sin(θ) are positive in the first and second quadrant, we have that for the given angle, θ = 65°, the range is therefore;

[tex]R = \dfrac{v \times sin(2\times 65 ^{\circ})}{g} = \dfrac{v \times sin(130 ^{\circ})}{g}[/tex]

The location of 130° = Second quadrant

A rotation of 130° in the counterclockwise is equivalent to a rotation of 50° in the clockwise direction

Therefore, we have sin(130°) = sin(50°)

Therefore, the range for 130°/2 = 65° is the same as the range for 50°/2 = 25° and an object launched from 65° will have the same range as an object launched from 25°.

You travel 50 meters at an angle of 37° North of East.
a) Calculate the Horizontal component.

Answers

Answer:

a)     x = 39.9 m

Explanation:

To find the components of a vector we can use trigonometric relationships. Since they indicate that the angle is 37º north of east, this angle is measured counterclockwise from the x-axis, therefore using trigonometry.

          cos θ = x / d

          sin θ = y / d

where the angle is 37º and the distance d = 50 m

          x = d cos θ

          y = d sim θ

let's calculate

        x = 50 cos 37

        y = 50 sin 37

        x = 39.9 m

        y = 30.1 m
