An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does havedevices to measure distance and time accurately. she lmows her own mass is 7& 4 kg, but she is unsure of the mass of alarge gas canister in the airless rocket, when this canister is approaching her at 3.50 m/s, she pushes against it, whichslows it down to 1.20 m/s (but does not reverse it) and gives her a speed of 240 m/s. (a) what is the mass of this canister? (b) how much kinetic energy is "lost" in this collision, and what happens to that energy?

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

do you have a picture of the table

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
