Answer:

Endothermic reaction

Explanation:

If the reaction releases less energy than the energy needed to start the chemical reaction, then the reaction takes energy from the system. An endothermic reaction is a reaction that will takes energy from the system. Those energies will be put into the product of the reaction, make the product have higher potential energy than the reactant. The product of this reactant will be less stable since it's at a high energy state.

AURORKA [14]

Answer:

Explanation:

Expression for relative velocity

= \frac{v_1+v_2}{1+\frac{v_1v_2}{c^2} }

= (.54 + .82 )c/ 1+ \frac{.54 \times.82}{1}

= 1.36 c / 1.4428

= .94 c

β = .94

A point on a wheel of radius 40 cm that is rotating at a constant 5.0 revolutions per second is located 0.20 m from the axis of
Margarita [4]

Answer:

197.2 m/s^2

Explanation:

The centripetal acceleration of a point moving by circular motion is given by:

a=\omega^2 r

where

\omega is the angular velocity

r is the distance from the axis of rotation

The point on the wheel makes 5.0 revolutions per second, so the frequency is

f=\frac{5}{1}=5 Hz

and the angular velocity is

\omega=2\pi f = 2\pi (5)=31.4 rad/s

While the distance of the point from the axis of rotation is

r=0.20 m

Substituting, we find the acceleration:

a=(31.4)^2(0.20)=197.2 m/s^2
