Find the magnitude and angle of a vector given the components: Bx = 7, By=-5​
Arte-miy333 [17]

Answer:

|B|  =  \sqrt{ {B _{x} }^{2} +  {B _{y} }^{2}  }  \\  =  \sqrt{ {7}^{2}  +  {5}^{2} }  \\  =  \sqrt{74}  \\  = 8.6

let \: the \: angle \: be \:  \theta \\  \tan(\theta)  =  \frac{B _{y} }{B _{x} }  \\  \tan( \theta)  =  \frac{ - 5}{7}  \\  \theta =  { \tan }^{ - 1} ( \frac{ - 5}{7} ) \\  = 35.5 \degree

"When the ball leaves the ramp at Point B, students measure the horizontal" distance traveled. They repeat the experiment five t
romanna [79]

Answer:

Speed of ball as it leaves ramp is 2 m/s

Explanation:

From the question it is given that the average distance traveled by ball from point A to B is 2.0 m and the time taken is 1sec

one student is using stopwatch to calculate the time taken by ball and another student is using meter stick to calculate the distance traveled

since speed of ball is given by v = \frac{distance}{time}  thus,

the speed = 2 m/s

now for minimizing the error of speed it is necessary to record the readings by single students at-least 5 times and take average

by doing this, the error of speed calculation will be minimum as the it decreases the error due to random error of system caused by taking the reading  by different students

A uniform rod of length 50cm and mass 0.2kg is placed on a fulcrum at a distance of 40cm from the left end of the rod. At what d
oksano4ka [1.4K]

Answer:

x = 45 cm

Explanation:

Given that,

The length of a rod, L = 50 cm

Mass, m₁ = 0.2 kg

It is at 40cm from the left end of the rod.

We need to find the distance from the left end of the rod should a 0.6kg mass be hung to balance the rod.

The centre of mass of the rod is at 25 cm.

Taking moments of both masses such that,

15\times 0.2=x\times 0.6\\\\x=\drac{3}{0.6}\\\\x=5\ cm

The distance from the left end is 40+5 = 45 cm.

Hence, at a distance of 45 cm from the left end it will balance the rod.
