Suppose a=3i-2j+k b=-i-4j+3k and c is avector lying along positive x axis with the property that a(b+c)=0 then find c?
il63 [147K]

The value of the c will be (0 i+0 j+0 k). c is a vector that is along the positive x-axis and has the condition a(b+c)=0.

<h3>What is a vector?</h3>

A vector is a quantity or phenomena with magnitude and direction that are independent of one another. The phrase also refers to a quantity's mathematical or geometrical representation.

Given ;

a=3i-2j+k

b=-i-4j+3k

Given property:

a(b+c)=0

-i-4j+3k ((-i-4j+3k)+c)=0

(3+8+3)(-i-4j+3k)c=0

14(-i-4j+3k)c=0

c=0 i+0 j+0 k

Hence, the value of the c will be (0 i+0 j+0 k).

A .183 kg ball is moving 18.8 m/s when it runs into a spring of spring constant 86.9 N/m. How much KE does the ball have when it
Lemur [1.5K]

Answer:

The value is  KE_B  = 20.59 \  J

Explanation:

From the question we are told that

   The mass of the ball is  m  =  183 \  kg

   The initial  speed of the ball is  u  =  18.8 \  m/s

    The spring constant is  k  =  86.9 \ N/m

     The compression distance is  x =  0.520 \ m

Generally the energy stored in the string is mathematically represented as

        E =  \frac{1}{2}  *  k  * x^2

=>     E =  \frac{1}{2}  *  86.9  * 0.520 ^2

=>      E =   11.75 \  J

Generally the kinetic energy of the ball is mathematically represented as

          KE_b  =  \frac{1}{2} * m * u^2

=>      KE_b  =  \frac{1}{2}  *  0.183 * (18.8 )^2

        KE_b  = 32.34 \  J

Generally the KE   the ball have when it has compressed the spring is mathematically represented as

          KE_B  =  KE_b -  E

=>        KE_B  =  32.34 - 11.75

=>        KE_B  = 20.59 \  J

An electron has an initial velocity to the south but is observed to curve upward as the result of a magnetic field. This magneti
tekilochka [14]

Answer:

<em>e) west</em>

<em></em>

Explanation:

According to Lorentz left hand rule, the left hand is used to represent the motion of an electron in a magnetic field. Hold out the left hand with the fingers held out parallel to the palm, and the thumb held at right angle to the other fingers. If the thumb represents the motion of the electron though the field, and the other fingers represent the direction of the field, then the palm will push in the direction of the force on the particle.

In this case, if we point the thumb to the south (towards your body), with the palm facing up, then the fingers will point west.
