It should be true: electrons low from negative toward positive to negative toward positive because opposite charges attract each other.
I hope this was correct
It’s C
Because C is a reflection which reflects something such as mirror

(a) Determine the circumference of the Earth through the equation,
C = 2πr
Substituting the known values,
C = 2π(1.50 x 10¹¹ m)
C = 9.424 x 10¹¹ m
Then, divide the answer by time which is given to a year which is equal to 31536000 s.
orbital speed = (9.424 x 10¹¹ m)/31536000 s
orbital speed = 29883.307 m/s
Hence, the orbital speed of the Earth is ~29883.307 m/s.
(b) The mass of the sun is ~1.9891 x 10³⁰ kg.
Answer:
Gold
Explanation:
Given:
Mass of sample = 63.5 g
Mass of water = 60.2 g
Find:
Object
Computation:
Mass of water displaced = 63.5 g - 60.2 g
Mass of water displaced = 3.3 g
So, volume in water = 3.3 cm³
Density = Mass / Volume
Density = 63.5 g / 3.3
Density = 19.24
So,
Object ,must be gold.
Answer:
A 0.25 kg beach ball rolling at a speed of 7 m/s collides with a heavy exercise ball at rest. The beach ball bounces straight back with a speed of 4 m/s. That is the change in momentum of the beach ball? What is the impulse exerted on the beach ball? What is the impulse exerted on the exercise ball?
Explanation:
the answer is impulse grenade from fortnite
