Vector sum of 15 m, East and 9 m, West is 24 m, East. True False

Answer:

False.

Explanation:

The sum of two vectors is given by :

S = a + b

As we know that vectors have both magnitude and direction. Let us consider that East points in +x axis and west points in -x axis. Let the sum is given by S. So,

S = 15 m + (-9 m)

S = 6 meters

So, the vector sum of 15 m, East and 9 m, West is 6 m not 24 m. Hence, the given statement is false.

Answer:

False

Explanation:

Because when you go through east

( +x axis ) then you go to west ( -x axis )

You will subtract -9 from +15

it's become +6

( I talk about the displacement not distance) ( West = - East )

I hope that it's a clear ") .

Which are properties of both a gas and a plasma? Check all that apply.
wlad13 [49]
<span>The answer is  4, 6 and 7. Gas and plasma share most similar properties. The difference lies in the fact that plasma is composed of ions and electrons (ionized  gas) as opposed to gas that is composed of neutral molecules. Therefore plasma can conduct electricity while gas cannot. </span>

A car is traveling at a velocity of 13.5 m/sec (30 mph) north on a straight road. The mass of the car is 1,000 kg. Calculate the
Nat2105 [25]

Answer:

<em> The momentum of the body would be 13500 kg .m/sec</em>

Explanation:

What Momentum Entails

momentum is a property that is possed by all moving objects, it is a product of mass and velocity. A moving object has a magnitude which is the mass of the body and direction which is the  velocity towards a certain direction, so it is a vector quantity

Step by Step Calculation

The momentum of a body can be gotten from the expression below;

p = m x v

where p is the momentum

m is the mass of the body = 1000 kg

v is the velocity = 13.5 m/sec

Given these parameters our momentum would be;

p = 1000 kg x 13.5 m/sec

p = 13500 kg . m/sec

Therefore the momentum of the body would be 13500 kg. m/sec

A student constructed a series circuit consisting of a 12.0-volt battery, a 10.0-ohm lamp, and a
vesna_86 [32]

I thought you were going to ask for the resistance of the unknown
series resistor.  Since you only want the equivalent resistance of the
circuit, you don't even need to know the resistance of the lamp.

I = E / R

Current through the circuit = (voltage of the battery) / (circuit resistance).
  
                                                  0.5 = (12) / R

Multiply each side by  'R' :    (0.5) R = 12

Multiply each side by  2 :      <em>R = 24 ohms</em>


(Since the resistance of the lamp is 10 ohms, the
unknown series resistor is the other 14 ohms.)

A football player throws and accelerates a ball (m = 0.150 kg) from rest to a velocity of 50 m/s in 0.0121 sec. Determine the ac
Rasek [7]

Answer:

Acceleration=4m/s²

Force applied =619.8N

Explanation:

Using equation of motion

V=u+at we have: u=o, v=50m/s

50= 0 + a×0.0121

a = 50/0.0121

a= 4m/s²

Neglecting resistance forces

F= ma, where a = v-u/t

F=m×(v-u)/t

F= 0.150 ×(50-0)/0.0121

F=7.5/0.0121

F= 619.8N
