Answer: when the full moon moves through Earth’s shadow, which only happens when Earth is between the Moon and the Sun and all three are lined up in the same plane, called the ecliptic In an eclipse, Earth’s shadow has two distinct parts the umbra and the penumbra. The umbra is the inner, cone-shaped part of the shadow, in which all of the light has been blocked. The penumbra is the outer part of Earth’s shadow where only part of the light is blocked. In the penumbra, the light is dimmed but not totally absent.

C) Radiopharmaceuticals
D) High Intensity Focused Ultrasounds
The treatment most likely to use is Superficial External bean Radiation Therapy. Then the correct option is B.
What is the electromagnetic spectrum?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.

what energy source would be the most cost efficient and have the smallest impact on the climate? evidence?
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.
True or False: A tree is an example of an object that contains chemical energy. help!! Please!! True False
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

how to use a circuit breaker
?
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)

Explain the difference between mass and weight and how they are measured.
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.

Two forces,one of 12 N and another of 24 N,act on a body in such a way that they make an angle of 90degree with each other.Find the resultant of the two forces
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.

A ball has 2 kg*m/s of momentum when thrown with a velocity of 8 m/s outwards. Find the mass of the ball.
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.
