Answer:

the higher the frequency the shorter the wave length

Explanation:

because all light waves move through a vacuum at same speed the number of wave crests passing by a given point in one second depends on the wavelength

A toy floats in a swimming pool. The buoyant force exerted on the toy depends on the volume ofa. none of these choices.b. all th
Citrus2011 [14]

Answer:c

Explanation:

The buoyancy force on toy depends upon the volume of toy under pool water.

According to Archimedes principle buoyant force on a floating body depends upon the weight of displaced liquid by object.

Buoyancy force is given by

F_b=\rho _f\times V\times g

where \rho _f=density of fluid

V=volume of object under water

g=acceleration due to gravity

Dan is gliding on his skateboard at 4.00m/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at 6
frozen [14]

To solve this problem we will apply the concepts related to the conservation of the Momentum. For this purpose we will define the momentum as the product between mass and velocity, and by conservation the initial momentum will be equal to the final momentum. Mathematically this is,

m_1u_1+m_2u_2 = m_1v_1+m_2v_2

Here,

m_{1,2} = Mass of Dan and Skateboard respectively

u_{1,2} = Initial velocity of Dan and Skateboard respectively

v_{1,2} = Final velocity of Dan and Skateboard respectively

Our values are:

Dan's mass

m_1 = 60kg

Mass of the skateboard

m_2 = 7.0kg

Both have the same initial velocity, then

u_1= u_2 = 4m/s

Final velocity of Skateboard is

v_2 = 6m/s

Rearranging to find the final velocity of Dan we have then,

m_1u_1+m_2u_2 = m_1v_1+m_2v_2

m_1v_1+m_2v_2 = (m_1+m_2)u_1

v_1 = \frac{ (m_1+m_2)u_1 -m_2v_2}{m_1}

Replacing,

v_1 = \frac{(60+7)(4)-(7)(6)}{60}

v_1 = 3.76m/s

Therefore Dan will touch the ground at a speed of 3.76m/s
