Which set of atoms will form an ionic compound?
Oksanka [162]

Answer:

The answer is A)

Explanation:

An ionic compound is formed when one atom donates one or more electrons to one or more atoms of another element. Calcium has two valence electrons, which are donated to an atom of oxygen. So, an ionic compound is formed in the reaction involving one calcium atom with an oxygen atom.

The position of a 60 g oscillating mass is given by x(t)=(2.0cm)cos(10t), where t is in seconds. determine the velocity at t=0.4
mrs_skeptik [129]

The position of an oscillating mass is given by:

x(t)=A cos (\omega t)

where A is the amplitude of the oscillation, \omega the angular frequency and t the time.

The velocity of the oscillating mass can be found by calculating the derivative of the position:

v(t)=x'(t)=-\omega A sin (\omega t)

In this problem, A=2.0 cm and \omega=10 rad/s, so if we substitute these data and t=0.4 s we can find the velocity at t=0.4 s:

v(t)=-(10 rad/s)(2.0 cm) sin ((10 rad/s)(0.4 s))=-13.07 cm/s=-0.13 m/s

After driving a portion of the route, the taptap is fully loaded with a total of 25 people including the driver, with an average
loris [4]

Answer:

0.4455 m

Explanation:

g = Acceleration due to gravity = 9.81 m/s²

Total mass is

m=62\times 25+15\times 3+5\times 3+25\\\Rightarrow m=1635\ kg

Here the spring constant is not given so let us assume it as k=36000\ N/m

Here, the forces are balanced

mg=kx\\\Rightarrow 1635\times 9.81=36000\times x\\\Rightarrow x=\dfrac{1635\times 9.81}{36000}\\\Rightarrow x=0.4455\ m

The springs are compressed by 0.4455 m
