What is the speed that is measured in speedometer to track speed violation?

Physics
1 answer:
BartSMP [9]3 years ago
4 0

Answer:

The officer's unit detects this 135-mile-per-hour speed and should subtract the patrol car's 70-mile -per-hour ground speed to get your true speed of 65 miles per hour. Instead, the officer's ground-speed beam fixes on the truck ahead and measures a false 50-mile-per-hour ground speed.

Explanation:

A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards.

What is a warming sign that suggest a weight loss plan is a fad diet rather than a healthy weight loss plan?
Serga [27]

Answer:

Warming signs before fad diet includes:

1. When a special type of diet is recommended for weight loss.

2. When quick weight loss is promised instead of advice on the need to exercise, eat healthy foods including fruits and vegetables, and adopt a good feeding behavior.

3. Promises rapid weight loss in a short period of time.

After taking the fad diet the following might be experienced:

1. Constipation.

2. Weakness and fatigue.

3. More accumulation of fats in the body in the long run after a short term normal  BMI (Body mass index).

4. Lower metabolic rates over time.

Explanation:

weight loss is a practice adopted by people for various reasons ranging from the desire to stay healthy to, ability to pursue a career that requires a good Body Mass Index. For instance, A BMI (Body mass index) which is equal to a person's weight (kg) / (height(m))^2 of 30 and higher is considered obese.

Fad diet which may give a temporary result of weight loss is not considered totally healthy as it doesn't capture the need to eat a healthy balanced diet instead focuses on more routine consumption of a particular kind of diet.

A healthy weight loss plan captures the need to exercise, reduce body fats while eating healthy. Eating fruits, vegetables are also encouraged.

Consider a 24.0 V storage battery that can transfer, over the course of its useful lifetime, a total charge equivalent to 340000
xeze [42]

Answer:

Explanation:

Given that,

Potential difference of battery is

V = 24V

Total charge battery can transferred

q = 340,000C

Work done by the battery?

Work done is given as

W = qV

Where q is charge in Columbs

V is potential difference in Volts

Then, W = qV

W = 340,000×24

W = 8,160,000 J

Work done by the battery over it's useful life time is 8,160,000J

Find the speed at which Superman (mass=78.0 kg) must fly into a train (mass = 17863 kg) traveling at 75.0 km/hr to stop it. Runn
lapo4ka [179]

Answer with Explanation:

We are given that

Mass of superman=m=78 kg

Mass of train=m'=17863 kg

Speed of train=u'=75 km/h=75\times \frac{5}{18}=20.8 m/s

1 km/h=\frac{5}{18} m/s

Let initial speed of superman=u

Momentum=mv

Using the formula

78u=17863\times 75

u=\frac{17863\times 75}{78}

u=17175.9 km/h

Average horizontal force=0.58

Deceleration a=-0.58\times 9.8=-5.68 m/s^2

Final speed of train=v'=0

v=u+at

Using the formula

0=20.8-5.68t

5.68t=20.8

t=\frac{v'-u'}{a}=\frac{0-20.8}{-5.68}

t=3.66 s

v^2-u^2=2as

Using the formula

0-(20.8)^2=2(-5.68)a

(20.8)^2=2(5.68)s

s={\frac{(20.8)^2}{2(5.68)}=38.1 m
