State the condition under which a satellite would move with escape velocity

Physics
1 answer:
elixir [45]3 years ago
7 0
When the launch velocity is a bit less than the escape velocity, the satellite with time will find itself back to earth and when the speed is far beyond the escape velocity, the satellite with time, be lost in space.

The velocity of escape from the less massive Moon is about 2.4 km per second at its surface. ... A planet (or satellite) cannot long retain an atmosphere if the planet's escape velocity is low enough to be near the average velocity of the gas molecules making up the atmosphere.

Which mystery primate is a biped? list the characteristics you choose to justify your answer
Vadim26 [7]

Primate B mystery primate is a biped.

The characteristics are:

  1. The vast majority of primates live in trees (Notable exceptions are humans and gorillas).
  2. The majority of primates have upright upper bodies and occasionally walk on two feet (Humans are erect and always exhibit bipedalism).
  3. All primates have smaller noses and matching olfactory brain regions (except Lemurs).
  4. Compared to other mammals, primates have enormous brains for their size. Stereoscopic vision, hand-eye coordination, and manual dexterity are all governed by the brain's enlarged regions.
  5. Considering the size of the animal, long gestations
  6. Primate sociality is rather high in general.
  7. The majority of primates are nocturnal.
  8. The highly enjoyable action of grooming is shared by all highly evolved primates, including humans.
<h3>Primate </h3>

Lemurs, lorises, tarsiers, monkeys, apes, and humans are all included in the biological order called primates. Class Mammalian of the phylum Vertebrate includes creatures with qualities that have evolved recently in the taxonomic classification of the animal kingdom. 19 subtaxa known as orders have been added to the Mammalia classification. Primates are one of such groups, which contains eutherian animals like monkeys and apes. As a result, during a period of 30 million years, new world and old world monkeys underwent different adaptive radiations and were reproductively isolated. The Oligocene epoch saw the evolution of prosimians. About 30 million years ago, all currently extant primates underwent evolution.

A meter stick is found to balance at the 49.7-cm mark when placed on a fulcrum. When a 41.0-gram mass is attached at the 23.0-cm
aev [14]

Answer:

mass of the meter stick=0.063 kg

or

mass of the meter stick=63.3 g

Explanation:

Given data

m₁=41.0g=0.041kg

r₁=(39.2 - 23)cm

r₂=(49.7 - 39.2)cm

g=9.8 m/s²

To find

m₂(mass of the meter stick)

Solution

The clockwise and counter-clockwise torques must be equal if the meter stick   is in rotational equilibrium

Torque_{cw}=Torque_{cw}\\F_{1}r_{1}=F_{2}r_{2}\\  m_{1}gr_{1}=m_{2}gr_{2}\\(0.041kg)(9.8m/s^{2} )(0.392m-0.23m)=m_{2}(9.8m/s^{2})(0.497m-0.392m)\\0.0651N.m=1.029m_{2}\\m_{2}=0.063 kg\\or\\m_{2}=63.3g

What happens along a stationary front?
oee [108]

Answer: b. The flow of air is neither toward the warm air mass nor toward the cold air mass.

A stationary front forms between two air masses. A stationary front results when the warm front or cold front air stops moving. This occurs due to the fact that warm front and cold front air masses being opposite to each other but neither of them are able to repel the other. This affects the climatic conditions of the region. The weather is often cloudy along a stationary front and also supported with fall of rain and snow especially if the air in the front is cold with low atmospheric pressure.

<em>Therefore, along a stationary front the flow of air is neither toward the warm air mass nor toward the cold air mass. </em>

you are given a 1/5 model of a car that normally runs at 30 mph. what wind tunnel speed should you use to test the car? (assume
julsineya [31]

The wind tunnel speed that must be used to test the car 1 / 5 model of a car that normally runs at 30 mph is 150 mph

Re = u L / ν

Re = Reynold's number

u = Flow speed

L = Characteristic linear dimension

ν = Kinematic viscosity

ν_{p} = 1.516 * 10^{-5} m² / s

ν_{p} = ν_{m} = 1.516 * 10^{-5} m² / s

L_{m} = L_{p} / 5

u_{p} = 30 mph

Re_{m} = u_{m} L_{p} / 5 * 1.516 * 10^{-5}

Re_{p} = 30 L_{p} / 1.516 * 10^{-5}

In tunnel,

Re_{m} = Re_{p}

u_{m} L_{p} / 5 * 1.516 * 10^{-5} = 30 L_{p} / 5 * 1.516 * 10^{-5}

u_{m} = 30 * 5

u_{m} = 150 mph

Therefore, the wind tunnel speed that must be used to test the car is 150 mph
