True.
The San Andreas fault, though it has not shaken for quite a few years, is, as scientists are saying, getting ready to create one of the largest earthquakes known. A sudden and destructive movement of plates can move the water located above, creating a large wave (tsunamis) that can overflow and flood parts of the Western Coast of the Americas.

Answer: Use the Right -hand Rule to find the direction of the magnetic field.
Explanation: A magnetic force only occur, in a magnetic field, when a particle is moving perpendicularly relative to the magnetic field. So, all three quantities are perpendicular among themselves.
The Right-Hand Rule apply for the positive charges moving in conventional current. If the moving charge is negative, the velocity must be reversed.
Right-Hand Rule determines the direction of any or all of the three and it is as follows: With you right hand, point your index finger in the direction of the velocity, your middle finger in the direction of the magnetic field and your thumb will be pointing in the direction of the magnetic force.
Another way of using the rule is when there is a current carrying wire:
The fingers of your right hand will curl into a half circle around the wire, they will point in the direction of the field. The thumb will point in the direction of the conventional current.
I think that when work is done and a force istransferred an object must move in the direction of the force.
Answer:
The Acceleration will increase
Explanation:
Newton's Second Law of motion: It states that the rate of change of momentum is directly proportional to the applied force and takes places along the direction of the force.
It can be expressed mathematically as,
F ∝ m(v-u)/t
Where (v-u)/t = a
F = kma.
F = force, m = mass of the body, a = acceleration, k = constant of proportionality which tend to unity for a unit force, a unit mass, and a unit acceleration.
Therefore,
F = ma.
From the equation above,
If the net force acting on a body increase, while the mass of the body remains constant, the acceleration will also increase.
Answer:
Teeth start developing in the unborn baby. Good nutrition from the mother during pregnancy is important in tooth development. The mother's diet should have adequate amounts of calcium, phosphorus, vitamin C, and vitamin D. Certain medicines (such as tetracycline) should not be taken during pregnancy. These can cause the unborn baby’s developing teeth to be discolored. There are 4 main stages of tooth development:
The first stage begins in the unborn baby at about 6 weeks of pregnancy (gestation). This is when the basic substance of the tooth forms.
Next, the hard tissue that surrounds the teeth is formed around 3 to 4 months of gestation.
After the child is born, the next stage occurs when the tooth actually sticks out (protrudes) through the gum.
Finally, the child loses the primary or baby teeth.
