Answer:
Jupiter has an internal heat source.
Explanation:
It is believed that most of this heat is the residual (left over) heat from the time when formation of early Solar nebula took place. Jupiter absorbs energy from the Sun in the form of light and the coverts it into heat and later releases this heat in the form of thermal radiation.
It is recorded that Jupiter emits almost twice amount of energy from the amount which it receives from the sun. It is this internal source of energy and sunlight which provide energy to Jupiter's atmosphere.
However, this phenomenon of internal heat source is also seen in other celestial bodies as well such as Saturn, Neptune, Stars, etc.
Answer:
N = 1471.5[N]
Explanation:
We must remember that anybody lying on a horizontal surface, the normal force is defined as the vector corresponding to the force of equal magnitude to the product of mass by gravity, but in the opposite direction to the vector of weight.
To calculate the magnitude of the normal force (equal to weight), we can perform the product of mass by gravity.
where:
w = weight [N] (units of Newtons)
m = mass = 150 [kg]
g = gravity acceleration = 9.81 [m/s²}
your velocity during the journey is 5,000 m/s
The given parameters;
- the initial position = 5,000 m East
- second position, = 3,000 m North
- final position, = 1,000 m West
The horizontal displacement = 5,000 m East - 1,000 m West = 4000 m
The vertical displacement = 3,000 m North
The resultant displacement is calculated as;
The velocity is the change in displacement per change in time;
Thus, your velocity during the journey is 5,000 m/s

Answer:
See answer below
Explanation:
Hi there,
To get started, recall the Center of Mass formula for two masses:
where m is mass and x is displacement <em>from the center of the shape.</em>
Since masses at the center of a geometric shape have a displacement (x) value of 0, as the mass is already of the center, and does not affect Xcm. So, we can disregard the central mass, hence we use the above formula for two masses.
We can arbitrarily define left to be a negative (-) displacement, and vice versa for right direction. We proceed with the formula:
Since we defined left (-) and right (+), we notice the center of mass is (+) value. This makes sense, as there is slightly more mass on the right side. Hence, you should place a support 1/6 of the rod's length away from the rod's center.
Study well and persevere.
thanks,
Answer:
1. 25%
2. You can move the skater higher up to increase the potential energy.
3. The kinetic energy increases because there is more motion.
Explanation:
1. If the total kinetic and potential energy is 100%, and we know that the kinetic energy is 75%, then we can find the potential by finding the missing value of this equation. Potential energy + kinetic energy =total energy.
? + 75%=100%
2. The higher an object is, the more potential energy it has because of the increase of its gravitational energy.
3. When an object is higher, there is more potential energy. As the skater goes down, the potential energy decreases which in turn increases the kinetic energy.
