Answer: element
Explanation:
Couldn't be a compound because contains same type of atoms. Can't be a mixture either because not physically mixed or anything. Isn't a solution ofc because oxygen is a gas.
Answer:
0.281 m
Explanation:
From vᵧ = uᵧ - gt
where vᵧ = final vertical component of the velocity
uᵧ = vertical component of the initial velocity = 2.5 m/s
g = 9.8 m/s²
At maximum height, vᵧ = 0 m/s
So,
Time to reach maximum height, t = uᵧ/g = 2.5/9.8 = 0.255 s
Total time of flight, T = 2 × time to reach maximum height
T = 2 × t = 2 × 0.255 = 0.510 s
Range of the cannon = uₓ T = 0.55 × 0.510 = 0.281 m
Note uₓ = horizontal component of the initial velocity.
Answer:
Explanation:
A.
Standing near the loudspeaker you cannot hear its frequency buy as the car moves away from it the frequency reduces.
Convert mL to gallons as follows:
355 mL = 0.355 L
0.355 L * (1 gal/3.785 L) = 0.0938 gallons
The equivalent km covered would be
57miles/gal * 0.0938 gal * (1.61 km/ 1 mile) = 8.61 kilometers
I hope I was able to help you. Have a good day!
Answer: 
Explanation:
Given
Current in the first wire 
Current in the second wire 
wires are
apart
Force per unit length between the current-carrying wires is

Force exerted by the wires is the same
Put the values

This force will be repulsive in nature as the current is flowing opposite
