Answer:
The strength of gravity on Pluto is 0.6 m/s²
Explanation:
The given mass of the shoe = 0.5 kg
The weight of the shoe (on Pluto), W = 0.3 N
Therefore, given that weight, W = Mass × The acceleration due to gravity, We have;
The strength of gravity = The force gravity applies to each unit of mass = The acceleration due to gravity (in m/s²)
The weight of the shoe, W = The mass of the shoe × The strength of gravity on Pluto
Substituting the known values, gives;
0.3 = 0.5 × The strength of gravity on Pluto
∴ The strength of gravity on Pluto = 0.6 m/s².
V₀=6.35*4=25.4 m/s the speed of the when car enters into main speedway
S=V₂t
S=73t - distance of the second car
S=V₀t+at²/2
S=25.4t+6.35t²/2 - distance of the first car
6.35t²/2+25.4t=73t
t*(3.175t-47.6)
3.175t=47.6
t=14.99 s
14.99 s is required for the first car to catch the second
Answer:
the nucleus of the atom you have conserved almost all its mass in a very small volume
Explanation:
In Rutherforf's experiment, most alpha particles had few deflections, eg a few of them were deflected at small angles, a much smaller number deflected at large angles, and very few were deflected.
The explanation that I found for this is that if all the mass and the positive charge of the atom is in a small volume, they could specifically calculate this the relationship of the volumes,
V_atom / V_nucleo = 10⁴
Therefore, the phrase that explains the observing phenomenon is that the nucleus of the atom has concentrated almost all its mass, very small emolument and in that same volume is all the positive charge of the atoms.
In summary, the phrase that describes the process is:
the nucleus of the atom you have conserved almost all its mass in a very small volume
Answer:
Just be your true authentic self. The more you try to be like someone else, or be a follower, or conform yourself to fit in, the less true to yourself you will be. Believe it or not, being different is attractive. Yet at the same time, nothing is really normal. We all have differences that make us unique; therefore no one is 100% normal. To "win friends" you just need to be you. It'll come naturally - even if you're an introvert. You don't necessarily need to try. You will find you're people someday. And that's a fact.
As for how to influence people, you really just need to make sure you're acting in a way that is inspiring. Think about things from a different perspective. Try to do your best and be your best self 24/7. You can change people's opinions just by being nice. You can remove people's grudges by lending a helping hand. You don't need to stop global warming, or discover a drug that can cure cancer to make a difference. The small things that you do, like holding a door for a stranger, or buying groceries for an elder in your neighborhood have an immeasurable impact. Try do more of these small things, and before long you'll notice your influence in your community and maybe even the world.
Above all, be you.
Answer:
Walking burns up more energy,1740000J
Explanation:
Given that the displacement is 5.0km, and running at 10km/h and uses, walking at 3km/hr and uses 290watts:
Energy consumption for running is calculated as:
Energy consumption for walking is calculated as:
Walking is a slower process hence the need for more energy over longer periods raltive to running the same distance.
Hence walking burns more energy; 1,740,000J. It burns more because you walk for a greater period of time.
