Daniddmelo says it right there, don't know why he got reported.
The potential energy (PE) is mass x height x gravity. So it would be 25 kg x 4 m x 9.8 = 980 joules. The child starts out with 980 joules of potential energy. The kinetic energy (KE) is (1/2) x mass x velocity squared. KE = (1/2) x 25 kg x 5 m/s2 = 312.5 joules. So he ends with 312.5 joules of kinetic energy. The Energy lost to friction = PE - KE. 980- 312.5 = 667.5 joules of energy lost to friction.
Please don't just copy and paste, and thank you Dan cause you practically did it I just... elaborated more? I dunno.
The answer is D.Competition with the Soviet Union spurred American space missions.

An organism scientific name consist of : C. its genus name and its species name
The first part of the name is taken from the Genus and the second part of the name is taken from the species
hope this helps
Answer:
When balloon moves in the downward direction two forces acts on it.
i) Force exerted by air in the upward direction
ii) Weight
According to newton’s second law of motion:
Sum of forces = Ma
W – F = Ma
Mg – F = Ma …….. (i)
when some of the mass m is dropped and balloon is moving in upward direction with acceleration a/2 then,
F – W = (M-m)a/2
F – (M-m)g = (M-m)a/2
F – Mg + mg = Ma/2 – ma/2 ….. (ii)
Adding equation (i) and (ii)
mg = M(3a/2) – ma/2
m(g + a/2) = M(3a/2)
m = M(3a/2)/(g + a/2)
Answer:
814.62 million kilometers
Explanation:
eccentricity of elliptical orbit =0.048
Let semi major axis of elliptical path be a.
From center of the ellipse focus is at a distance = a*eccentricity
Now, closest approach from focus is = a(1-e)
After plugging values = a(1-0.048)=740.52
a=777.31 million kilometers
Maximum distance from sun (apihalian) =a+a*e =a(1+e)
= 777.31(1+0.048)
=814.62 million kilometers
