Answer:

y = 3.26 [m]

Explanation:

In order to solve this problem, we must use the following equation of kinematics.

[tex]v_{f}^{2}= v_{o}^{2}-2*g*y[/tex]

where:

Vf = final velocity = 0

Vo = initial velocity = 8 [m/s]

g = gravity acceleration = 9.81 [m/s²]

y = elevation [m]

Note: The negative sign in the equation above represents that the movement is againts the direction of the gravity acceleration.

Now replacing:

[tex]0=8^{2} -2*9.81*y\\19.62*y=64\\y=3.26 [m][/tex]

Answer:

Electromagnet.

Explanation:

Electric bulb and electric water heather are application of heating effect of electric current. The electromagnet is not the result of heating effect of electric current. The bulb gives light due to the heating effect similarly the water is heated or warmed by the heating effect of electric current.

Answer:

An unbalanced force can change an object's motion. An unbalanced force acting on a still object could make the object start moving. An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving.

Answer:

THE CORRECT ANSWER IS OPTION ( c )Pulmonary aortic valve

Explanation:

Pulmonary aortic valve is not a component of systemic circuit.

Systemic circuit is a part of circulatory system that help to transport blood to different part of the body. It transport blood from the left ventricle to the capillaries and then other part of the body.

Therefore, Pulmonary aortic valve is not a component of systemic circuit.

Answer:

I believe the answer is C

Explanation:

because centripetal force is generally assosiated with rotation and how fast something spins

Torque is the measure of how effectively a force causes rotation because centripetal force is generally assosiated with rotation and how fast something spins.

Torque is a pattern of the force that can make a victim to revolve on an axis. The torque's direction vector based on the force's direction on the axis.

The SI unit of torque is the Newton-meter. The Torque can be both static or dynamic.

A static is one that does not generate an angular acceleration.

The  Torque's magnitude vector ζ for a torque generated by a given force F is;

ζ = F .r sin(θ)

where,

r is the width of the moment arm

θ is the angle within the force vector and the moment arm.

In rotational kinematics, torque is measured as;

ζ = Iα

Where,

α is the angular acceleration

I is the rotational inertia

therefore, Torque is the measure of how effectively a force causes rotation because centripetal force is generally assosiated with rotation and how fast something spins.

Answer:

Here's why this is correct

According to BrightHubEducation, Machines make work easier by changing the size of force, direction of force, or distance the force acts on. Lifting a car with a flat tire and loosening the lug nuts can be accomplished by a single person thanks to simple machines. The jack and lug wrench are simple machines that alter the force needed to change the tire.

Answer:

The linear speed is 6.51 m/s

Explanation:

Uniform Circular Motion

It's a movement of an object along the circumference of a circle. It can also be defined as a rotation along a circular path.

The angular speed can be calculated as follows:

[tex]\displaystyle \omega=\frac{v}{r}[/tex]

Where:

v = tangential or linear speed

r = radius of the circle described by the rotating object

To calculate the linear speed, solve for v:

[tex]v = \omega\cdot r[/tex]

[tex]v = 21\ rad/s\cdot 0.31\ m[/tex]

[tex]v = 6.51\ m/s[/tex]

The linear speed is 6.51 m/s

B. an organism being changed through technological methods

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments. One of the most important branch of science is bioengineering. Bioengineering can be defined as a high-tech process which avail scientists the opportunity or ability to modify, remove, replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.

Selective breeding has been used to create plants that are more resistant to disease. Thus, this is an example of an organism being changed through technological methods.

I dont see a mark where it is, if there was a line it would be marking the constant speed of it. There is just time(s) which probably stands for speed, and position(m) which probably stands for miles. There is a measurement of 50, down to 10.

Answer:

Centripetal acceleration = 8m/s²

Explanation:

Given the following data;

Radius, r = 50m

Velocity, v = 20m/s

To find centripetal acceleration;

Centripetal acceleration = v²/r

Centripetal acceleration = 20²/50

Centripetal acceleration = 400/50

Centripetal acceleration = 8m/s²

Therefore, the centripetal acceleration of Zach's car is 8 meters per seconds square.

Answer:One of this country's most notable achievements will be spending Canada Day weekend marking its own milestone anniversary in a unique place, floating up in space.

After 10 years in the ether, several times farther from Earth than the International Space Station, it remains the world's smallest space telescope.

MOST was also Canada's first-ever space telescope when it was launched into space on June 30, 2003.

It has helped make Canada a leader in the field of micro satellites.

But Matthews is particularly enthused about all the other possibilities that might be opened up by the 60-kilogram MOST.

The colorful University of British Columbia astrophysicist firmly believes there is life outside our solar system.

"Certainly simple forms of life like microbial life is probably very common — and I hope complex life," Matthews said in a recent interview. "If it's out there, we're finding the places where it's most likely to live."

I have no Idea if this helps but hope it does.

Answer:

a. 12.57 m/s b. 39.5 m/s² c. Her centripetal force is four times her weight.

Explanation:

a. What is Missy's linear speed on the rotor?

Missy's linear speed v = 2πr/T where r = radius = 4.0 m and T = time it takes to complete one revolution = 2.0 s

So, v = 2πr/T

= 2π(4.0 m)/2.0 s

= 4π m/s

= 12.57 m/s

b. What is  Missy's centripetal acceleration on the rotor?

Missy's centripetal acceleration, a = v²/r where v = linear velocity = 12.57 m/s and r = radius = 4.0 m

a = v²/r

= (12.57 m/s)²/4.0 m

= 158.01 m²/s² ÷ 4.0 m

= 39.5 m/s²

c. If her mass is 50-Kg, how is the centripetal force  compare to her weight?

Her centripetal force F = ma where m = mass = 50 kg and a = centripetal acceleration = 39.5 m/s².

Her weight W = mg where m = mass = 50 kg and g = acceleration due to gravity = 9.8 m/s².

So, comparing her centripetal force to her weight, we have

F/W = ma/mg

= a/g

= 39.5 m/s² ÷ 9.8 m/s²

= 4.03

≅ 4

So her centripetal force is four times her weight.

The velocity vector is always perpendicular to the radius. By radius, I mean the inward centripetal force that pulls the object to continue on its curved path. Without this inward force, the object would continue on a straight path tangential to the curve it was previously on.
