Answer:

Some planets have seasons some don't bc of the distance from the sun some of them are too cold or too hot to have seasons

If a wave travels 16 meters in 2 seconds, what is its wave speed?

GarryVolchara [31]

Wave speed is 8 m/s

Explanation:

Wave speed or speed of the wave is given by the formula

v = distance traveled by the wave/time

Here, distance traveled = 16 m and time = 2 s

⇒ Wave speed = 16/2 = 8 m/s

What is the main difference between velocity and speed?

Marina86 [1]

Speed is scalar, meaning it's only going to be like 74 mph, doesn't matter which direction. Velocity is a vector, meaning it has direction. You can go -74mph when talking about velocity, not speed.

Answer:

the faster an object moves the more kinetic it has. the more mass an object has, the more kinetic energy it has.

An object has traveled 20 meters in 40 seconds what is its average speed

Mice21 [21]

Hello,

To solve we need to know the formula for speed

The formula is D/T=S (Distance of time=speed)

Now all we have to do is plug in the numbers.

20/40= 1/2 or 0.5

SO the speed is 0.5 m/s

Have a great day!

a mass of 0.30kg is attached to a spring and is set in motion with a period of 0.24 s. what is the spring constantof the spring

IrinaK [193]

Answer:

The spring constant of the spring is 205.42 N/m.

Explanation:

Springs have their own natural "spring constants" that define how stiff they are. The letter k is used for the spring constant, and it has the units N/m.

k = -F/x

The period of a spring-mass system is proportional to the square root of the mass and inversely proportional to the square root of the spring constant.

Given:

mass of object in SHM = m = 0.30 kg

Time period of the spring mass system = 0.24s

Spring constant = k ?

Finding 'k' using Time period 'T':

We know that $T = 2pi\sqrt{\frac{m}{k} }$

$\frac{T}{2pi} = \sqrt{\frac{m}{k} }\\ \frac{T^{2} }{4(3.14)^{2} } = \frac{m}{k}\\ k = \frac{m*4*9.86}{T^{2} } \\k = \frac{0.3*4*9.86}{0.24^{2}}\\k = 205.42 N/m}$
