Image result for what does a worm and wheel mechanism do to torque and speed
Like other gear arrangements, a worm drive can reduce rotational speed or transmit higher torque. ... Each full 360 degree turn of a single start worm advances the gear by one tooth. For a multi start worm the gear reduction equals the number of teeth on the gear divided by the number of starts on the worm.

An object accelerates from rest to a velocity of 34 m/s
over a distance of 70 m. What was its acceleration?
Answer:
6.8m/s²
Explanation:
Given parameters:
Initial velocity = 0m/s
Final velocity = 34m/s
Distance = 70m
Unknown:
To solve this problem we apply one of the motion equations;
V² = U² + 2aS
where V is the final velocity
U is the initial velocity
a is the acceleration
S is the distance covered
Input the parameters and solve;
34² = 0² + 2 x a x 70
34² = 140a
a = 6.8m/s²
What acceleration will all objects experience during their flights through the air (on Earth)?
Answer:
d
Explanation:
Answer:
9.8 m/s/s
Explanation:
As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity

Suppose you are climbing a hill whose shape is given by the equation z = 2000 − 0.005x2 − 0.01y2, where x, y, and z are measured in meters, and you are standing at a point with coordinates (60, 40, 1966). The positive x-axis points east and the positive y-axis points north. (a) If you walk due south, will you start to ascend or descend? ascend descend Correct: Your answer is correct. At what rate? Correct: Your answer is correct. vertical meters per horizontal meter (b) If you walk northwest, will you start to ascend or descend? ascend descend Correct: Your answer is correct. At what rate? (Round your answer to two decimal places.) Correct: Your answer is correct. vertical meters per horizontal meter (c) In which direction is the slope largest? What is the rate of ascent in that direction? vertical meters per horizontal meter At what angle above the horizontal does the path in that direction begin? (Round your answer to two decimal places.)
Answer:
(a) Ascend at 0.8 vertical meter/meter
(b) Descend at -0.2·√2 vertical meter/meter
(c) In the (-0.6, -0.8) direction. The path begins at 45° to the horizontal
Explanation:
The given equation of the shape of the hill is z = 2000 - 0.005·x² - 0.01·y²
The current location = (60, 40, 1966)
The direction of the positive x-axis = east
The direction of the positive y-axis = north
(a) Walking due south = Reducing the y-value 40
From the equation, the elevation varies inversely with the motion towards the north
Therefore, walking south increases the elevation, and we ascend
The rate is given by the partial derivative at in the -j direction, which is 0.02
The rate is therefore 40 × 0.02 = 0.8
(b)The unit vector in the northwest direction u = 1/√2·(-1, 1)
∴ The rate = (-0.01(60), -0.02(40))·u = (-0.6, -0.8)·1/√2·(-1, 1) = -0.2·√2
Therefore we descend
(c) The slope is largest in the grad of the function at the point (60, 40) which is given as follows;
d(2000 - 0.005·x² - 0.01·y² )/dx, d(2000 - 0.005·x² - 0.01·y² )/dy = (-0.6, -0.8)
Therefore, the direction is tan⁻¹(-0.8/-0.6) ≈ S 36.87° W
The slope =(√((-0.4)² + (-0.8)²) = 1
Therefore, the angle is 45° to the horizontal.

Arrange the following events in the mantle convection process. Use numbers 1-5.
a. Lithospheric plates move in the asthenosphere due to rising and sinking of
materials.
b. The decomposition of radioactive elements causes heat in the interior part of
the Earth
c. Heat slowly rises to the mantle and creates convection current.
d. Heat moves to the core.
e. The process repeats as cycle.
Answer:
1) Lithospheric plates move in the asthenosphere due to rising and sinking of materials is 1.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core
5) The process repeats as cycle.
Explanation:
Mantle convection is the gradual slow creeping of movement of the Earth's mantle which is as a result of convection current which transfer heat from the interior to the surface of the Earth .
The process of mantle convection start with
1. Lithospheric plates move in the asthenosphere due to rising and sinking of materials is and thus form the two component of the mantle.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth. This is as a result of accretion which is associated to sea flooding
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core, cools down by conduction and convection of heat.
5) The process repeats as cycle.
The proper and correct arrangement of events in the mantle convection process are:
1. The decomposition of radioactive elements causes heat in the interior part of the Earth.
2. Heat moves to the core
3. Heat slowly rises to the mantle and creates convection current.
4. Lithospheric plates move in the asthenosphere due to rising and sinking of materials.
5. The process repeats as a cycle.
Convection is considered to be one of the most efficient ways through which heat is transported from the interior of planet Earth to the surface.
Mantle convection can be defined as the very slow transfer of heat due to the movement of Earth's solid silicate material within the mantle.
Basically, the slow creeping of the mantle causes a transfer of heat from the white-hot core to the brittle lithosphere during mantle convection.
Furthermore, the heating of the mantle takes place from below (the core) and it rises upward in hotter regions while it sinks down in colder regions.
The proper and correct arrangement of events in the mantle convection process are:
1. Heat is caused in the interior part of the Earth due to the decomposition or decay of radioactive elements.
2. Heat moves to the core.
3. Heat slowly rises from the Earth's core to the mantle and creates convection current in the asthenosphere, which is the plastic layer of the mantle.
4. Lithospheric plates move in the asthenosphere due to rising and sinking of materials.
5. The process is then repeated as a cycle.

a phosphorus atom needs to gain ---electrons to achieve a full octet
Answer:
Three (3).
Explanation:
The octet rule is a rule in chemistry that states that, chemical elements would either gain or loss electrons in their outermost shell in order to attain a stable electronic configuration i.e having eight (8) valence electrons in their outermost shell such as chemical elements found in group 8 (2-8-8) known as noble gas.
A phosphorus atom needs to gain three (3) electrons to achieve a full octet because the atomic number of phosphorus is 15 and as such it has the electronic configuration of 2-8-5 and needs three electron in order to become a stable element.

A sock with a mass of 0.03 kg is stuck to the inside of a clothes dryer spins
around the drum once every 0.5 sec at a distance of 0.5 m from the center of
the drum. What is the linear speed if the sock could fly out?*
Answer:
15.71 m/s
Explanation:
We are given;
Time; t = 0.2 s
Radius; r = 0.5 m
The circumference will give us the distance covered.
Formula for circumference is 2πr
Thus; Distance = 2πr = 2 × π × 0.5 = π
Linear speed = distance/time = π/0.2 = 15.71 m/s
