Answer:Although the crust is solid, the core of the Earth is surrounded by a mixture of molten iron and nickle. The magnetic field of Earth is caused by currents of electricity that flow in the molten core. These currents are hundreds of miles wide and flow at thousands of miles per hour as the earth rotates. hope it helped in someway ig idk
Explanation:
Answer:
355 m/s
Explanation:
Distance = 605 km
Initial speed = = 284 m/s
Final velocity = = 426 m/s
Average speed = ?
There is two method two find average speed. In first method, using 3rd equation of motion, we find acceleration.
Then using first equation of motion, we find time
Then using the formula of average velocity, we find average velocity
Second method is very simple
355 m/s
ok i can help you what are your questions
Answer:
a) 0.0537 kg, 0.877 m
b) 609 m/s²
c) 4.35 kg
Explanation:
B = ρ(air).V(g)
Assuming g(m) is the "g" for Mars.
For a sphere, V = 4/3πR³.
Surface area of a sphere is A = 4πR²
Thus, the mass of the balloon is (4.5*10^-3 kg/m²) (4πR²)
