Answer:
New acceleration is 20.0 m/s².
Explanation:
F = m*a
F = 0.35 kg * 10.0m/s²
If Force will be doubled , and mass will be the same
we can write
2F = 2*0.35 kg*10.0 m/s²=0.35kg*20.0m/s²
New acceleration is 20.0 m/s².
Answer:
height from where rock was thrown is 27.916 m
Explanation:
speed = 7.50 m/s
θ = 30°
g= 9.8 m/s²
horizontal distance = 18 m
time require for vertical displacement
t = 2.8 sec
now for calculation of height
s = ut + 0.5 a t²
-h = v sinθ× t + 0.5 ×(-9.8)× (2.8²)
-h = 7.5 sin30°× 2.8 - 0.5 ×(9.8)× (2.8²)
-h = -27.916 m
h= 27.916 m
height from where rock was thrown is 27.916 m
Answer:
C. Constant
Explanation:
The total energy of the cannonball remains constant as it travels through the air.
Answer:
hydrophilic
Explanation:
hydrophobic means it hates water so a hydrophobic material would separate from the water and just sit there (an example of this is oil)
This resistance current is directly proportional to voltage and inversely proportional to resistance. In other words, as the voltage increases, so does the current. Hope this helps !!
