Nothing accelerates a Projectile Horizontally during Motion...
Consequently
Horizontal Acceleration is Always Zero.
The Horizontal Velocity is always Constant too.
Only the vertical Velocity changes by -9.8ms-².
If this is so...
∆x = v'∆t + ½(0)(∆t)²
∆x = v't.
I'd go with Option D.
The displacement of Edward in the westerly direction is determined as 180.27 km.
<h3>Displacement of Edward</h3>
The displacement of Edward is calculated as follows;
R² = a² + b² - 2abcosθ
R² = 150² + 200² - 2(150 x 200) x cos60
R² = 32500
R = 180.27 km
Thus, the displacement of Edward in the westerly direction is determined as 180.27 km.

It would be a physical change because the properties of the red food colouring would not actually affect the chemical properties of the bleach.
Answer:
, assuming that there's no heat exchange between the washing machine and the environment.
Explanation:
Let denote the mass of water and the specific heat capacity of water. The energy required to raise the temperature of that much water by would be:
.
Washing at would require a temperature change of .
Washing at would require a temperature change of .
In both situations, while .
Calculate the energy required in either situation:
Washing at :
.
Washing at :
