Provided the projectile is landing at the same elevation as it is launched from, it is 45 degrees
Answer:
(a) Girl acceleration = 0.15 m/s², (b) Sled acceleration = 0.93 m/s²
Explanation:
Given:
M1=Mass of girl = 43 Kg
M2= mass of Sled = 7.1 Kg
Force F= 6.6 N
To Find (a) a1 = girl acceleration (b) a2 = sled acceleration
Solution:
F1 = F2 = F (Newton's 3rd Law)
F=ma (Newton's 2nd Law)
(a) F = M1a1
⇒a1 = F/M1 = 6.6 N / 43 Kg = 0.15 m/s²
(b) a2 = F / M2 = 6.6 N / 7.1 Kg = 0.93 m/s²
Horizontal angulation is Select one: a. the side-to-side angulation. b. different when using the paralleling and bisecting techniques.
Angles that are horizontal. relates to the central ray's placement in a horizontal, or side-to-side, plane.
A picture with an overlap of nearby structures in the horizontal plane is produced by situating the central ray such that the horizontal angulation is not directed through the interproximal contacts of the adjacent teeth (the contact areas of the teeth are superimposed over each other).
Fracture angulation refers to a particular kind of fracture displacement in which the bone's natural axis has been changed so that the distal end now points off in a different direction. When using a bite-wing tab, the x-ray beam's center ray must be pointed at the contact points between teeth. The x-ray beam must be centered on the receptor to guarantee that the receptor is exposed.

Explanation:
This should be of help:
An atom is made up of three subatomic particles:
- Protons are the positively charged particles.
- Electrons are the negatively charged particles.
- Neutrons do not carry any charges.
A neutral atom is an atom that has not lost or gained any amount of electrons.
In a neutral atom;
the number of protons and electrons are the same
Usually atoms are designated this way:
ᵃₙX
where X is the symbol of the atom
a is the mass number of the atom
n is the atomic number of the atom
The mass number = number of protons + number of neutrons
Atomic number = number of protons
Note; atomic number is the same as the number protons and the number of electrons in a neutral atom.
