Answer:

2+ charge

Explanation: The alkaline earth metals have two valence electrons in their highest-energy orbitals (ns2). They are smaller than the alkali metals of the same period, and therefore have higher ionization energies. In most cases, the alkaline earth metals are ionized to form a 2+ charge

Hope this helps, have a great day :)

A mass attached to the end of a spring is oscillating with a period of 2.25 s on a horizontal frictionless surface. The mass was

Rudiy27

Answer:

$X=0.0389m$

Explanation:

From the question we are told that:

Period of spring $T_s=2.25s$

Initial Position of Mass $x=0.0480m$

Final Mass period $T_f=5.85s$

Generally the equation for the Mass location is mathematically given by

$X=xcos*\frac{2\pi T_s}{T_f}$

$X=0.048*cos*\frac{2\pi 5.85}{2.25}$

$X=0.0389m$

A machine exerts a 100 N force to the right over a 5.00 meter length in 4.00 seconds. Calculate the power output of this machine

bixtya [17]

125 W is the power output of this machine.

Answer:

Explanation:

Power is defined as the amount of work done on the system to move that system from its original state within the given time interval. So it can be determined by the ratio of work done with time interval. As work done is the measure of force required to move a system to a certain distance. Work done is calculated as product of force with displacement.

So in the present case, the force is given as 100 N, the displacement is given as 5 m and the time is given as 4 s, then power is

$Power = \frac{Work done}{Time}$
