Explain What the core muscles do and why it's important to have a strong set of core muscles.
Answer: Core muscles protect the spine and keeps it stabilized. Also they can help control movements such as walking and standing. The core helps transfer energy and help us move in different directions. It's important to have a strong set of core muscles.
Explanation:
Answer:
The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.

Calculate the running costs of a filament lamp with a 60 W bulb and a CFL lamp with a 15 W bulb for 15 hours.
1 kWh costs 10p.
cost = power (kW) × time (hours) × price (per kWh)
Answer:
the cost of running the bulbs is 11.25p
Explanation:
Given;
cost of running 1 kwh = 10 p
power of filament bulb, P = 60 W
power of the CFL bulb, P = 15 W
time of power consumption, t = 15 hours
Total Energy consumed;
E = (60W + 15W) x 15 hours
E = (75)(15)
E = 1125 Wh
E = 1.125 kWh
Cost of 1.125 kWh = 1.125 x 10p
= 11.25p
Therefore, the cost of running the bulbs is 11.25p
Your teacher gives you samples of the following elements. Which sample is shiny but does not conduct heat and electricity well? (DOK 2)
A.
fluorine (F)
B.
silver (Ag)
C.
germanium (Ge)
D.
neon (Ne)
Fluorine is the sample which is shiny but does not conduct heat and electricity through it. The flow of electricity requires the flow of electrons or charged particles. Thus, the correct option is A.
What are conductors?
A conductor is a substance, chemical element, or a material which allows electricity and heat to flow through it. In a conductor, the electrical charge carriers which are usually electrons or positive and negative ions, move easily from one atom to another atom when a particular amount of voltage is applied.
Fluorine is a shiny element however it does not conduct heat and electricity through it. It is the most electronegative atom and is very reactive in nature. It only gains electrons and does not lose them. And because of this property of fluorine, it restricts the movement of electrons through it and fails to conduct electricity.
Therefore, the correct option is A.

A group of friends are going bowling. They discuss how ball weight and speed can change the amount of
kinetic energy transferred to the pins.
They can use a 6 pound, 10 pound or 12 pound ball.
They can roll the ball at 10 miles per hour (beginner), 14 miles per hour (intermediate) or 18 miles per hour (professional) speed.
A. Describe a strategy that they could use to transfer the greatest amount of kinetic energy to the pins.
B. Explain the relationship between kinetic energy and strategy that you chose in part A.
C. Draw a model that demonstrates the energy transfers that occurred in the system.
Answer:
A. you would want to use the 12 ound ball and the 18 mph speed in order to transfer the most kinetic energy
B. KE= 1/2 MV^2 so you would want to maximize both your Mass(weight of the ball) and Velocity(speed of the roll) in order to achive the greatest KE.
C. see image

A 55 kg skier is at the top of a slope. The vertical distance between start and finish is 10m. (a) What is her Potential Energy? (b) How fast is she moving at the bottom of the hill?
Explanation:
Given that,
Mass of a skier, m = 55 kg
The vertical distance between start and finish is 10 m.
(a) The potential energy of a skier is given by :
[tex]E=mgh\\\\E=55\times 9.8\times 10\\\\=5390\ J[/tex]
(b) When she reaches the bottom of the hill, the potential energy is converted to kinetic energy. So,
[tex]5390=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2\times 5390}{55}} \\\\v=14\ m/s[/tex]
Hence, her potential energy is 5390 J and at the bottom of the hill she is moving with a speed of 14 m/s.
How can a volcano develop in the middle of a tectonic plate?
Answer:
Volcanoes that form away from plate boundaries are created by hotspots. A hotspot is an area in the mantle that is believed to be somewhat hotter than the surrounding material. The rising magma from the hotspot can push its way through the crust and burst out at the surface, forming a volcano.
Explanation:
Volcanoes can form in subduction zones, which are regions where tectonic plates are interacting one and plate is sinking beneath the other.
Essay about how volcanoes form.A volcano is a hill or mountain in the shape of a cone that is erected around a fissure in the surface of the earth thru which heated gases, rock fragments, and lava are released. A conical mass grows around the conduit as the solid fragments gather there, becoming progressively larger until it reaches the size of a gigantic volcanic mountain.
Explain what a volcano is.A volcano is an aperture or vent through which magma, tephra (small rocks), or steam are released onto the the planet's surface. Days, weeks, or even years might pass between outbursts of volcanoes.
