Answer:

The higher an electromagnetic wave's frequency, the lower its wavelength.

Explanation:

The frequency of a electromagnetic wave is given by the following relation :

$c=f\times \lambda$

Where

c = speed of light

f = frequency of a wave

$\lambda$ = wavelength

$f=\dfrac{c}{\lambda}$

It is clear that the frequency of a wave has inverse relationship with its wavelength. So, higher the electromagnetic wave's frequency, the lower its wavelength.

Suppose a 49-N sled is resting on packed snow. The coefficient of kinetic friction is 0.11. If a person weighing 585 N sits on t

Andre45 [30]

Answer:

69.74 N

Explanation:

We are given that

Weight of sled=49 N

Coefficient of kinetic friction $,\mu_k=0.11$

Weight of person=585 N

Total weight==mg=49+585=634 N

We know that

Force needed to pull the sled across the snow at constant speed,F=Kinetic friction

$F=\mu_k N$

Where N= Normal=mg

$F=0.11\times 634=69.74 N$

Hence, the force is needed to pull the sled across the snow at constant speed=69.74 N
