Answer:
okay so what you will do is where is says red giant you will write all about what it talks about red giants only, and the box plantary nebulas you will write about what is says about only planetary nebulas. x- hope this helps :)
Explanation:
the spring will be compressed by 0.3072 m
Explanation:
acceleration of elevator=3 m/s²
mass of student= 60 Kg
spring constant=2.5 x 10³ N/m
the force on the student is given by F = m ( g +a)
F=60 (9.8+3)
F=768 N
now the formula for spring force is given by
F= k x
768= 2.5 x 10³ (x)
x=0.3072 m
Answer:
The person must be located in the Equator Line. The maximum centripetal acceleration experienced by a person is 0.0337 meters per square second.
Explanation:
Physically speaking, the centripetal acceleration (
), measured in meters per square second, experienced by a person is defined by the following expression:
(1)
Where:
- Angular speed of the Earth, measured in radians per second.
- Distance perpendicular to the rotation axis, measured in meters.
Since rotation axis passes through poles and distance described above is directly proportional to centripetal acceleration. The person must be located in the Equator Line, which is equivalent to the radius of the planet.
In addition, the angular speed of the Earth can be calculated in terms of its period (
), measured in seconds:
(2)
If we know that 
and 
, then the maximum centripetal acceleration experienced by a person is:
The maximum centripetal acceleration experienced by a person is 0.0337 meters per square second.
Answer:
Gastrocnemius
Explanation:
The twin, called the gastrocnemius muscle, in relation to the foot causes plantar flexion and leg flexion.
Said muscle is the main engine in the propulsion of the march, bearing large loads. That is why when it comes to practicing sports, it is very helpful to carry out preventive work for gastrocnemius using eccentric loads in addition to using stretching techniques.
This is located on the back of the leg, being the most superficial of the calf. It is located on the soleus muscle and extends from the femoral condyles to the calcaneal tendon.
Condyles are understood as rounded heads that fit in the hole to form the joints.
The twin is a biarticular muscle since its path crosses two joints, that of the knee and ankle.
Its function on the knee is to stabilize the femur, to avoid that there is an imbalance forward in the flexion movements. While, on the ankle acts as an extensor of the same with tendency to investment.
