Visible light waves are the only electromagnetic waves we can see has the longest wavelength
2 The greater the force applied on an object, the greater it's acceleration
3 You can find the mass of an object if you know it's acceleration and the forces acting on it
4 Force is equal to the product of mass and acceleration
Answer:
1. The mass will change depending on the force.
Explanation:
We know that the newton's second law of motion gives the relation between the mass (m) of an object, force (F) applied and the corresponding measure of acceleration (a) of the object. This can be expressed in the form of an equation:
F = ma
Thus force is the product of mass and acceleration. Using this equation we can derive mass of an object, if acceleration and force values are known.
In the given equation, mass is a constant value and mass will not change in any case. Therefore force is directly proportional to amount object will be accelerated. With the increase in force applied on object, amount the object accelerated will increase and vice versa
true or false the state of a medium helps determine the speed of sound passing through a medium
nuclear energy
B.
electrical energy
C.
chemical energy
D.
sound energy
The correct answer to the question is : C). Chemical energy.
EXPLANATION:
A gas stove provides energy when the gas present inside it, is burnt.
The gas contained inside it are natural gases which contain chemical energy. When gases come under fire or electric spark, the chemical energy is converted into light and heat energy.
No nuclear, electric or sound energy are consumed in providing power .
Hence, the correct statement is chemical energy.
The star'scolor is an important property of stars because it provides some information about the temperature of a star. The correct option is C.
A star'shue depends on its temperature; cooler stars seem red, while hotter stars appear blue or white.
This is due to the fact that although stars emitlight over the full spectrum, the predominant hue in the light that we perceive is the color that corresponds to the star's temperature.
The other stated characteristics, such as a star's name, distance from the star, and shape, have no direct bearing on a star's temperature.
However, these characteristics can also provide crucialdetails about the star, such as its size, brightness, and location in the sky.
Thus, the correct option is C.
