Answer:

It is True

Explanation:.

A  commander assigns a zone reconnaissance mission when he seeks additional information on a zone before committing other forces in the zone. It is appropriate when the enemy situation is vague,  existing knowledge of the terrain is limited, or combat operations have altered the terrain. A zone  reconnaissance could include several route or area reconnaissance missions assigned to subordinate units.

If a motorcyclist accelerates from rest to 40 m/s in 8 seconds, what is their acceleration?
IgorC [24]

Answer:

5 m/s²

Explanation:

Given:

v₀ = 0 m/s

v = 40 m/s

t = 8 s

Find: a

a = (v − v₀) / t

a = (40 m/s − 0 m/s) / 8 s

a = 5 m/s²

An 8000-kg engine pulls a 40,000 kg train along a level track and gives it an acceleration a1 = 1.20 m/s 2 . What acceleration (
mel-nik [20]

a = F/(m1+m2)
1.2 = F/48,000
F = 57,600N

a = F/(m1+m3)
a = 57,600/24,000
a = 2.4 m/s^2

A 1,155 kg truck has a velocity of 18 m/s. What is the momentum of the truck?
77julia77 [94]

The momentum of truck is 20790 kg m/s

<em><u>Solution:</u></em>

Given that we have to find the momentum of truck

From given, 1155 kg truck has a velocity of 18 m/s

Therefore,

Mass = 1155 kg

Velocity = 18 m/s

<em><u>The momentum is given by formula:</u></em>

p = m \times v

Where, m is mass in kg and v is velocity in m/s

Substituting the values we get,

p = 1155 \times 18\\\\p = 20790

Thus momentum of truck is 20790 kg m/s

How long was a 50 W lightbulb left on for if 500,002 J were burned?
saveliy_v [14]

" 50 W " means " 50 Watts "  or  " 50 Joules per second ".

(500,002 J) / (50 J/sec)  =  <em>10,000.04 seconds</em>

(That's 2 hours 46 minutes 40.04 seconds.)
