Answer:

Energy is absorbed in the reaction.

Explanation:

When energy of reactants is greater than the energy of products then there is need to provide energy to break the bonds of reactants. Such kind of reactions are called endothermic reactions. Hence, if in a reaction, energy of reactants is greater than the energy products then energy will absorb in that reaction.

Answer:

In an endothermic reaction, the products have more stored chemical energy than the reactants. In an exothermic reaction, the opposite is true. The products have less stored chemical energy than the reactants. The excess energy in the reactants is released to the surroundings when the reaction occurs.

When 10 N force applied at 30 degrees to the end of a 20 cm handle of a wrench, it was just able to loosen the nut. What magnitu
fredd [130]

Answer:

<h2>5N</h2>

Explanation:

To get the magnitude of the force would require to just loosen the nut, if the force apply perpendicularly at the end of the handle, we will have to resolve the force perpendicular to the wrench. Torque is the turning effect of a body or force about a point. It is similar to moments.

Torque = Force * radius

Note that the force must be perpendicular to the wrench. On resolving the force perpendicularly to the wrench, we will have to resolve the force to the vertical.

Fy = Fsinθ

Fy = 10sin30°

Fy = 10 * 0.5

Fy = 5N

<em>Torque = Fy * r</em>

<em>Given Fy = 5N and r = 20cm = 0.2m</em>

<em>Torque = 5 * 0.2</em>

<em>Torque = 1Nm</em>

<em />

<em>Hence the magnitude of the force would require to just loosen the nut, if the force apply perpendicularly at the end of the handle is 5N</em>

If I decrease the wavelength of an electromagnetic wave what will happen to the frequency of the wave?
Vinil7 [7]

This can be viewed as a decrease in the wavelength of the wave. A decrease in wavelength at a constant speed is associated with an increase in frequency since waves follow the equation v=f*λ, where λ is the wavelength and f is the frequency.
