It’s either movement or work or that’s what a quizzie said
Answer:
2000 pieces
Explanation:
The number of tiles is given by dividing the area of room by the area of each tile. In this case,
thw areas are as shown below
Area of room is 8*10= 80 m2
Converting dimensions of tiles from cm to m then
Area of tiles is 0.2*0.2= 0.04 m2
No of tiles is 80/0.04=2000 tiles
Answer:
R = 3.88 m
Explanation:
As the Chinook salmon leaves the water till it gets back into the water it is performing a projectile motion with the following parameters:
V₀ = Launch Speed = 6.7 m/s
θ = Launch Angle = 29°
R= Range of Projectile= Horizontal Distance Covered by Chinook salmon= ?
The value of the range of a projectile is given by the following formula:
R = (V₀² Sin 2θ)/g
R = [(6.7 m/s)² Sin {(2)(29°)}/(9.8 m/s²)]
R = [(6.7 m/s)² Sin (58°)/(9.8 m/s²)]
<u>R = 3.88 m</u>
Answer:
Heat, Let me explain,
Explanation:
An exothermic reaction is like... Lighting a candle so it produces a small amount of heat in less than a second and then normal heat.
Answer: d
Explanation:
For an object to move in a uniform circular motion, only force that acts on it is the centripetal force which acts along the line joining the object and center of the circular path. The acceleration also acts in the direction of force. The centripetal acceleration acts along the radius of the circular motion path.
In the given horizontal circle, the direction of the acceleration of the object points towards d.
