They are most likely immune to the pesticide and a stronger one needs to be created i hope that helps
Answer:
Salts
Explanation:
When acids reacts with bases, salts and water are usually the product of such reactions. This reaction is called neutralization reaction.
A salt is an ionic compound which consists of positive and negative ions. Here, appropriate aqueous acid reacts with a water soluble base or water insoluble base. The product is usually salt and water.
Answer:
a = 200 m/s²
Explanation:
Given,
The initial speed of rocket-powered sled, u = 0
The final speed of rocket-powered sled, v = 440 m/s
Time taken to reach final speed, t = 2.20 s
The acceleration of the body is given by the change in velocity by time
a = (v - u) / t
= (440 - 0) / 2.20
= 200 m/s²
Therefore, the acceleration of the rocket-powered sled, a = 200 m/s²
Answer:
Explanation:
The initial kinetic energy will be increased by the loss of potential energy and be decreased by the work of friction.
½mv₁² = ½mv₀² + mgh - Fd
½70v₁² = ½(70)14² + 70(9.8)(30) - 13(440)
v₁ = 24.9112... ≈ 25 m/s
The gravitational coupling between the Moon and the Earth's tidal bulge
is causing the Moon to slowly move farther away from the Earth.
The friction of the Earth's rotation inside the tidal bulge is causing the Earth
to rotate slightly slower, making the day slightly longer.
