Select the correct answer.
Which hand is negatively charged?

There is a basic difference, because mass is the actual amount of material contained in a body and is measuredin kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth

Mass is the matter in a material, while weight is the measure of how the force of gravity acts upon that mass.

Answer:

4.08m

Explanation:

h = PE/mg

h = 600/(15)(9.8)

h = 600/147

h = 4.08m

Answer:to protect an electrical circuit from damage caused by excess current from an overload or short circuit.

Explanation:

Answer:

the heat of the light.

Explanation:

no matter the light, there's always heat being produced from it. and heat makes liuqid rise

Answer:

As, we know momentum = mass × velocity that is p = mv

we have momentum (p) = 2 kg m/s

and velocity (v) = 8 m/s

so substitute values in p=mv

2 kg m/s = m × 8 m / s

m = 2 / 8 kg = 0.25 kg

Therefore, mass of substance is 0.25 kg.

2/8 in fractional form.....

Answer:

Is a tree an example of chemical energy?

Take, for example, an apple tree. The tree absorbs light energy from sunlight, converting the light energy into chemical potential energy stored in chemical bonds. The tree uses this energy to build leaves and branches and fruit. ... Then it takes that heat and converts it into motion, or kinetic energy

Explanation:

Answer:

circuit breakers work in a similar way to fuses, and also protect the circuit from damage if too much current flows but work in a different way. when circuit breakers detect a surge in current in a circuit, they break the circuit by opening a switch. one type of circuit breaker used instead of a fuse and an earth wire is a Residual Current Circuit Breaker (RCCB)

they are right it's mixture

Answer:

Force = Mass x Acceleration. Since the acceleration of gravity is always constant at 9.81 m/s2, the force of gravity is constant as well, according to Newton. If the object is sitting motionless on the ground, then the net force (sum of all forces) acting on it is zero

Answer: Solar energy and wind energy both can be used

Explanation: Solar energy as well as wind energy would be the most preferable energy source for this community.

Solar energy is the energy that is directly derived from the sun and can be transformed into electrical energy. For example, the use of solar panels.

Wind energy is obtained by the natural agent known as wind. In the region where the wind is high, the turbines moves very fast, thereby generating electricity. For example, wind mill.

Thus this two energy sources are less costly and have lesser environmental impacts and they are very precise and is currently rising in the faster rate and with innovative technical upgradation.

The treatment most likely to use is Superficial External bean Radiation Therapy. Then the correct option is B.

The electromagnetic spectrum consists of the range of all types of EM radiation. Radiation is a packet of energy that travels and spreads out.

It has radio waves, infrared waves, visible light waves, ultraviolet rays, and microwaves.

They possess high energy even to penetrate deep within the material. the electromagnetic spectrum has a longer wavelength and less frequency.

Haley noticed a small spot on her skin that turned out to be skin cancer.

Surgery, radiation, chemotherapy, and hormone therapy can all be used to relieve signs and symptoms.

Medications may relieve symptoms such as pain and shortness of breath. Palliative treatment can be used.

Answer:

Helium nuclei will split to form hydrogen and the sun will no longer release energy.

Explanation:

:)

When all the hydrogen in the sun has gone for fusion, helium nuclei will split to form hydrogen and the sun will continue to release energy.

The term nuclear fusion has to do with the combination of two or more nuclei to obtain a larger nuclei with the emission of a tremendous amount of energy.

Hence, when all the hydrogen in the sun has gone for fusion, helium nuclei will split to form hydrogen and the sun will continue to release energy.

Answer:

26.83 N.

Explanation:

If the angle between two vector is 90°, to get the resultant, we use Pythagoras theorem.

a² = b²+c²......................... Equation 1

Where a = R = Resultant, b =  12 N, c = 24 N.

Substitute these values into equation 1

R² = 12²+24²

R² = 144+576

R² = 720

√R² = √720

R = 26.83 N.

Hence, the result of the two force is 26.83 N.
