This is dependent on how many shells/layers/energy levels the element has. The first shell can only hold 2 electrons however every shell beyond that can hold 8 electrons
Answer:
6.33 km/s
Explanation:
Given that :
A spaceprobe in outer space is flying with a constant speed = 1.530 km/s.
The probe has a payload = 1363.0 kg
which carries 3486.0 kg of rocket fuel.
Exhaust speed = 3.795 km/s
How fast will the spaceprobe travel when all the rocket fuel is used up?
As we know that the rate of change of spaceprobe momentum is equal to the thrust of the rocket.
Then;
where;
= exhaust speed
Taking the integral of the above expression; we have:
= 6.33 km/s
Answer:
I believe that the crab would have 14 arms if the octopus had 12 arms
Explanation:
Answer:
6 with force advantage
Explanation:
The following data were obtained from the question:
Load = 300N
Effort = 50N
Mechanical advantage =.?
Mechanical advantage is defined by the ratio of load that of the force (effort) applied. It is represented mathematically as:
Mechanical advantage = load/effort
Using the above equation, we can obtain the mechanical advantage of the lever as follow:
Mechanical advantage = load/effort
Mechanical advantage = 300/50
Mechanical advantage = 6
Since a force force was applied to raised the load, therefore, the mechanical advantage is 6 with force advantage.
Answer:
C = 1256.63 miles
Explanation:
This problem is solved by using the following formula for the relation between the arc length of a circle and its radius:
s: arc length
r: radius
In this case "s" is 600 miles, and the angle of the arc length is 3°. With this information you can calculate the radius of the planet X:
With the value of the radius of the planet you can calculate the circumference, by using the following formula:
