Answer:
The distance from her hands to the kite is 60.4 feet.
Explanation:
Given that,
Kendra holds the string from the ground = 3 feet
Distance of kite from the ground = 35 feet
Suppose the angle is 32°.
According to the figure,
We need to calculate the distance from her hands to the kite
Using formula of angle
Put the value into the formula
Hence, The distance from her hands to the kite is 60.4 feet.
Answer:
The melting point of a substance referst to the temperature at which it changes state from solid to liquid. Therefore, the statement "The melting point of glycerine is 13 degree celsius" means that when the temperature at which glycerine is subjected is equal or higher than 13 degree celsius, it changes state from solid to liquid.
For example, the melting point of water is 0 °C. It means that when the temperature is higher than 0°C water goes from solid (Ice) to liquid. We all have seen that, right? ✔️
The magnitude of the vertical force that a concrete support exerts on the bridge at the far end is 201.25 N.
<h3>What is force?</h3>
The force is an action of push or pull which makes a body to move or stop.
Given is the weight of tourist W = 805 N and L is the length of the bridge.
Let the reaction force at both the ends of the bridge is R1 and R2.
Taking the moments about point A,
R1 x 0 - W x L/4 +R2 x L =0
R2 = W/4
R2 = 805 /4
R2 = 201.25 N
Thus, the magnitude of the vertical force that a concrete support exerts on the bridge at the far end is 201.25 N.
