Momentum = Mass * velocity

For the stationary football player, his velocity = 0

Momentum = 75 kg * 0 = 0 kgm/s

The second player =  70kg * 6 m/s = 420 kgm/s

The first player has no momentum, the second player has a momentum of 420 kgm/s

Momentum of an object = (its mass) x (its speed) .

Since speed is a factor of momentum, an object that
isn't moving doesn't have any.

-- The moving player has momentum. 

-- The stationary one doesn't.

To span the distance between two switches, why is adding an intermediate switch not an attractive choice
navik [9.2K]

Adding an intermediate switch is not an attractive choice to span the distance between two switches due to expense issues. It may have different ports.

<h3>What is a network switch?</h3>

A switch refers to a hardware tool capable of connecting different computer devices in a network.

A network switch can connect devices on a network by centralizing communications among many devices in a given local area network.

A switch may support different speeds for transmission of data (for example, one gigabit Gbps per second).

How much heat is needed to raise the temperature of a 100.0g of water by 85.0 c?
KatRina [158]

Answer:

35.7kJ

Explanation:

we can calculate the amount of heat energy required , using this formula

Q = mcθ

where.

Q = heat energy (Joules, J)  

m = mass of a substance (kg)  

c = specific heat capacity (units Jkg^{-1} C^{-1})

θ  = change in temperature (Celcius,C or Kelvin K)

Assume Specific heat capacity (c) of water =4200Jkg^{-1} C^{-1}

mass =0.1 kg

Q=0.1 kg*4200Jkg^{-1} C^{-1}*85C\\=35700J\\=35.7kJ
