Answer:
1. The answer is that there will be more force with more speed.
2. less speed means less force.
3. And last, but certainly not the least, the less the mass has, the less the force will be, unless the object is moving at a high speed.
Explanation:
Answer:
Final temperature of the copper is 59 degrees Celsius
Explanation:
It is given that,
Mass of the sample of copper metal, m = 6.5 g
Initial temperature of the metal,
Heat generated, Q = 84 J
The specific heat capacity of liquid water is 0.38 J/g-K
Let is the final temperature of the copper. It can be calculated using the definition of specific heat of any substance. It is given by :
or
So, the final temperature of the copper is 59 degrees Celsius. Hence, this is the required solution.
Answer:
The weight will be smaller than on Earth.
Explanation:
We call weight, to the product of the mass times the acceleration produced on this mass, due to the Universal law of gravitation.
This acceleration can be obtained applying Newton’s 2nd Law to the gravitational attractive force, as follows:
Fg = G m1m2 / (r12)2 = m1* a → a= G m2 / (r12)2 =g
If we take a planet with the same mass, but a larger size, this means that the distance, from the planet’s surface to the center, will be larger also.
As the gravitational attraction is inversely proportional to the square of the distance, this means that the acceleration caused by this force, will be smaller than on Earth.
As the mass is an universal constant, this means that the weight (as measured on a scale as the normal force) will be smaller also.
Answer:
4.0208 x 10^16 meters
Explanation:
speed of light in m/s * # seconds in a year * 4.25 years =
2.99792 x 10^8 * 3600*24*365.25 * 4.25 = 4.0208 x 10^16 m
Answer:
The gravitational force between a mass and the Earth is the object's weight. Mass is considered a measure of an object's inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg.
