Luis wanted to know which of his 4 toy cars is the fastest. He conducted an experime and recorded his results in the table shown

below.
CAR TRACK 1 TRACK 2 TRACK 3
1 2.0 s 2.3 s 4.0 s
2 2.5 s 3.0 s 4.5 s
3 4.0 s 4.6 s 8.0 s
4 1.5 s 2.0 s 3.5 s

Rasek [7]

Answer:

0.65  kg*m/s and 0.165 kg*m/s

Explanation:

Step one:

given data

mass m= 0.5kg

initial velolcity u=1.3m/s

final velocity v= 0.97m/s

Required

The change in momentum

Step two:

We know that the expression for impulse is given as

Ft= mv

Ft= 0.5*1.3

Ft= 0.65  kg*m/s

The expression for the change in momentum is given as

P= mΔv

substitute

Pt= 0.5*(1.3-0.97)

Pt= 0.5*0.33

Pt=0.165 kg*m/s

The telescope that allowed astronomers to discover most of the planets found with the transit method was called:.
kvasek [131]

Answer:This quest took a huge leap forward in 2000 when Hubble studied the exoplanet HD 209458 b, the first extrasolar planet known to make “transits” across the face of its star. Hubble became the first telescope to directly detect an exoplanet's atmosphere and survey its makeup.

For supernova explosions caused by collasping cores, the core itself will either become a __________ or a ___________. (choose t
Gnesinka [82]

When supernova explodes because of the collapsing cores, the core itself will become a neutron star or a white dwarf without undergoing any kind of explosive transformation. The white dwarf stars can also become supernova if they orbit another star in a binary system and steal material from their companion. In addition, the end state of a star, whether it will explode as a supernova become a black hole.

a tractor pulls a wagon from rest with a constant force of 700 N eventually giving the wagon a speed of 20 km/h. how much work i
Semenov [28]


Work = Force × distance

We need to calculate distance travelled.

20km/hr = 20,000m / 60min  → 333.3m/ min

333.3 × 3.5 min = 1,166.6 meters travelled

Force = 700 N  and distance = 1,166.6 m

Work done is  700 N × 1,666.6 =  816,620 Nm

Power output = work /time

Power output is 816, 620 Nm / (3.5 × 60sec) →816, 620 / 210 = 3,888.7

Power output is 3,888.7 Watts.

Power output can also be expressed in joules per second so it is also correct to  say work done is 3,888.7 J/s
