I don't think so.
Before I can accept that rumor, I'll need to see the signed testimony of
two reputable adult witnesses, who have no connection to any business
that profits in any way from the production, sale, or consumption of food,
and who will swear in a public meeting, presided over by three respected
members of their community, that they personally saw more than one of
the alleged beakless double-breasted chickens in the same place at the
same time.
A photo is not acceptable ... not for me, and not for the two witnesses.
Answer:
The temperature that would satisfy is 286.7°C
Explanation:
Given data:
d = 20 mm = 0.02 m
Le = characteristic length = 0.02/4 = 5x10⁻³m
K = 0.3 W/m K
ρCp = 1040 kJ/m³ K = 1.04x10⁶
t = 3 min = 180 s
h = 10 W/m² K
According transient heat analysis:
200°C is the limiting temperature, the temperature should not be less to 200°C, then, we suppose a temperature of 210°C (10°C), and find the temperature:
Answer:
Force F = 1535.86 N
the force necessary for his wife to hold onto their child during the collision is 1535.86 N
Explanation:
Given;
Mass of toddler m = 13 kg
Velocity v = 37 mi/h = 37 × 0.44704 m/s = 16.54 m/s
Impulse time t = 0.14 seconds
Using the impulse momentum equation,
Impulse = change in momentum
Ft = m(∆v)
Force F = m(∆v)/t
∆v = 16.54 m/s
F = 13×16.54/0.14
Force F = 1535.86 N
According to the elastic conservation momentum
m1v1 + m2v2 = m1V1 +m2V2
v: velocity before collision, V after collision
<span>the magnitude of the final velocity of the red marble
</span>m1v1 + m2v2 = m1V1 +m2V2
V2 is the final velocity we must find
V2 = 1 / m2 ( m1v1 + m2v2 - m1V1)
= 1/1.2 (3.5x15 + 1.2x 3.5 - 3.5x 5.5)= 63.29 cm/s
Answer:
Explanation:
The radio signals must travel for t=4 hours at 
. Since an hour has 60 minutes and a minute has 60 seconds we have that 4 hours are 4(60)(60) seconds = 14400s. We have the speed of light c=300000000m/s, so we use the definition of velocity in terms of distance travelled and time taken v=d/t , which in our case is v=c, and solving for d we have:
