Explanation:

SI base units are the set of units to measure physical quantities given by international system of units.

Here, we need to write the SI base units for the following quantities.

1. The mass of a sports car  : Kilogram (kg)

2. The diameter of a pizza  : meters (m)

3. The mass of a single slice of pepperoni  : Kilogram (kg)

4. The distance from your home to school  : meters (m)

5. Your mass : Kilogram (kg)

Hence, this is the required solution.

A electromagnetic wave of light has a wavelength of 500 nm. What is the energy (in Joules) of the photon representing the partic
marissa [1.9K]

Answer:

Energy, E=4.002\times 10^{-19}\ J

Explanation:

It is given that,

Wavelength of the photon, \lambda=500\ nm=5\times 10^{-7}\ m

We need to find the photon representing the particle interpretation of this light. it is given by :

E=\dfrac{hc}{\lambda}

E=\dfrac{6.67\times 10^{-34}\times 3\times 10^8}{5\times 10^{-7}}

E=4.002\times 10^{-19}\ J

So, the energy of the photon is 4.002\times 10^{-19}\ J. Hence, this is the required solution.

A shank has a moment of inertia about the knee joint of 0.18 kg∙m^2. Assume that the quadriceps muscles (vasti and the rectus fe
timofeeve [1]

Answer:

Torque will be equal to 4.176 N-m

Explanation:

It is given moment of inertia about knee joint I=0.18kgm^2

Angular acceleration produced \alpha =23.2rad/sec^2

We e have to find the torque

Torque is equal to \tau =I\alpha , here I is moment of inertia and \alpha is angular acceleration.

Torque will be equal to \tau =0.18\times 23.2=4.176Nm

So torque is equal to 4.176 N-m

Explain mantle convection.
inysia [295]

Answer:

Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.

The terminal velocity of a person falling in air depends upon the weight and the area of the person facing the fluid. Find the t
AVprozaik [17]

Answer:

v=115 m/s

or

v=414 km/h

Explanation:

Given data

A_{area}=0.140m^{2}\\  p_{air}=1.21 kg/m^{3}\\  m_{mass}=80kg

To find

Terminal velocity (in meters per second and kilometers per hour)

Solution

At terminal speed the weight equal the drag force

mg=1/2*C*p_{air}*v^{2}*A_{area}\\   v=\sqrt{\frac{2*m*g}{C**p_{air}*A_{area}} }\\ Where C=0.7\\v=\sqrt{\frac{2*9.8*80}{1.21*0.14*0.7} }\\ v=115m/s

For speed in km/h(kilometers per hour)

To convert m/s to km/h you need to multiply the speed value by 3.6

v=(115*3.6)km/h\\v=414km/h
