Plans are in place for crewed missions beyond Low Earth Obit and the Moonwards Mars. A new rocket has been designed for this mission. The rocket has a mass of 3.0 20 kg and can exert a thrust torce)
3520" N The rocket has been designed to have the stages so some parts can bejenisoned her the
rocket launch
a ta rocket is to escape the gravitational atraction of Earth must accelerate and reach what is termed
te escape verbory of 20.000 km
What is the intal upwards acceleration of the rocker? Show your workings
4 mars
Assuming the force remains constant, explain why a multistage rocket can reach escape velocity
more easy than a single stage rocket

A crewed mission to Mars would involve a spacecrat that would intalyorbit Mars at a height of 210
makes 62 minutes to Orbit Mars once
Given that the radius of the Mars is 3390 km and assuming a circular orbit, what is the orbital
speed of the spacecrat around the centre of Mars Show your workings

the answer is a. at the equator

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
