Answer:
242.19702 N
578.46718 N
681.02785 N
Explanation:
M = Mass of the corresponding planet
r = Radius of the corresponding planet
g = Acceleration due to gravity = 9.81 m/s²
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
Mass of person
Mass is the property of an object, it is constant irrespective of the forces acting on it so the mass of the person on each planet would be the same.
Gravitational force on Mars
Magnitude of the gravitational force Mars would exert on the man if he stood on its surface is 242.19702 N
Gravitational force on Venus
Magnitude of the gravitational force Venus would exert on the man if he stood on its surface is 578.46718 N
Gravitational force on Saturn
Magnitude of the gravitational force Saturn would exert on the man if he stood on its surface is 681.02785 N
Answer:
V = x/t
where:
x = distance [m]
t = time [s]
V = velocity [m/s]
Explanation:
Speed is defined as the distance travelled by a body in a given time interval. The velocity or speed is a vector, that is, it has magnitude and direction.
By virtue of its vector character, the direction of the displacement and the module, which is called speed, must be considered to define the velocity.
<u>Average speed</u>
The average speed is defined as the change of position over a given time interval. It is calculated by dividing the displacement vector (Δx) between the time interval (Δt) used.
<u>Instant speed</u>
Instantaneous velocity is a vector tangent to the trajectory, corresponding to the derivative of the vector position relative to time.
It allows to know the speed of a mobile that moves on a trajectory when the interval of time is infinitely small, being then the space traveled also very small, representing a point of the trajectory. Instant velocity is always tangent to the trajectory.
Density = mass/volume. 5000/50= 100 grams per cubic centimeter. No substance on Earth has anywhere near that density. Tops is about 20 for osmium and gold.
Answer:
Half life of S = 3.76secs
Explanation:
The concept of half life in radioactivity is applied. Half life is the time taken for a radioactive material to decay to half of its initial size.
For part 1 - How much signal will be degraded in 1secs = 1/3.9 = 0.2564
for part 2 - How much signal will be degraded in 1secs = 1/104 = 0.009615
Simply say = 1/3.9 + 1/104 = 0.266015
So both part 1 and part 2 took 1/0.266015 = 3.76secs is the half life of S when both pathways are active
