Answer:
Mass is how much "stuff" is in something. Weight is a force that is measured in Newtons. A pan balance is a type of scale. A measuring cup is used to measure volume, such as cups and grams (depending if you use the metric system or not).

Answer:
Maximum acceleration will be equal to 
Explanation:
We have given coefficient of kinetic friction 
And coefficient of static friction 
Acceleration due to gravity 
When truck moves maximum force will be equal to 
It is given that half of the weight is supported by its drive wheels
So force required 
From newtons law maximum acceleration will be equal to 
Answer:
a) its frequency
Explanation:
The color of visible light depends only on its frequency, not on the amplitude. In fact, the visible light spectrum can be classified into different colors according to the different frequencies:
Violet: 680-790 THz
Blue: 620-680 THz
Cyan: 600-620 THz
Green: 530-600 THz
Yellow: 510-530 THz
Orange: 480-510 THz
Red: 405-480 THz
And the color of the light has nothing to do with the amplitude of the wave. Therefore, the correct answer is
a) its frequency
Answer: 
Explanation: In a mass-spring-damper system, the differential equation that rules the motion of the mass is: mx" + cx' + kx = 0
Using m = 4, k = 24 and c = 20, we have
4x" + 20x' + 24x = 0
Simplifying, we have
x" + 5x'+ 6x = 0
The characteristic equation of this differential is

The solutions for the quadratic equation are:
and 
Hence:
x(t) = 
x'(t) = 
To determine the constants, we have the initial conditions x(0) = 4 and
x'(0) = 2, then:


Substituing the constants:

The position function for this system is: 
Explanation:
speed of curved path=under root of Mew and gravity
smooth surface Mew=0
so under root of 0×g
=0
