-- Radio waves.  (To hear the weather while I'm waking up.)

-- Light waves.  (To see where the dog is so I don't step on him.)

-- Infrared waves. (To make my toast for breakfast.)

-- Microwaves.  (To heat my oatmeal for breakfast.  Also when I go in to my job as a microwave communications engineer.)

An applied force of 50 N is used to accelerate an object, that weighs 73 N, to the right across a frictional surface. The object
Hunter-Best [27]

Answer:

5.38 m/s^2

Explanation:

NET force causing the object to accelerate  =  50 -10 = 40 N

Mass of the object =  73 N / 9.81 m/s^2 = 7.44 kg

F = ma

40 = 7.44 * a         a = 5.38 m/s^2

Diffrence between FMRI and MRI?
love history [14]
FMRI creates the images or brain maps of brain functioning by setting up and utilizing an advanced MRI scanner in such a way that increased blood flow to the activated areas of the brain shows up on the MRI scan. The MRI scanners do not actually detect blood flow or other metabolic processes.

what is the force constant, in newtons per meter, needed to produce a period of 0.45 s for a 0.011-kg mass on the spring?
topjm [15]

The force constant is 2.145 N/m.

<h3>What is spring constant?</h3>
  • The spring constant is the force required to stretch or compress a spring divided by the distance traveled by the spring. It is used to determine whether a spring is stable or unstable.
  • K is the proportionality constant, also known as the 'spring constant.' Hooke's law (F = -kx) specifies stiffness and strength via the k variable. The greater the value of k, the greater the force required to stretch an object to a given length.

Using the relation;

T = 2π√m/k

T = time period = 0.45 s

m =  mass of object in kilograms = 0.011kg

k = spring constant

To find k based on the formula,

k = 4 × (3.142)^2 × 0.011 / (0.45 )^2

k = 2.145 N/m

Therefore the force constant is 2.145 N/m.

A âsleeping policemanâ is a bump placed in the road to restrict the speed of cars. What radius of curvature should the bump have
asambeis [7]

To solve this problem, the concepts related to the balance of forces must be applied. In this case the two forces that must be in balance are the Weight and the centripetal force. Both forces are derived from Newton's second law, one of the linear movement and the other of the angular movement. The centripetal force is given by the function

F_c = \frac{mv^2}{R}

Here,

m = mass

v =Velocity

R = Radius

And the force product of the weight is given under the function

F_w =mg

Here,

m = Mass

g = Gravity

As both forces are in balance we will have

\sum F =0

F_w - F_c = 0

F_w = F_c

mg = \frac{mv^2}{R}

R = \frac{v^2}{g}

Speed would be

V = 40km/h (\frac{1000m}{1km})(\frac{1h}{3600s})

V = 11.11m/s

Replacing

R = \frac{11.11^2}{9.8}

R = 12.59m

The radius must be 12.6m

Why in the absence of air do all objects fall at the same rate?
geniusboy [140]

Answer:

objects falling at same rate.

Explanation:

ifif you neglect air resistance, objects following your Earth's surface or with the same approximate acceleration 9.8 meters per second squared (9.8 m/s^2, or g) due to Earth's gravity.
