Answer:

Hello! Here are your answers!

SCALAR: Scalar quantities have a size or magnitude only.

VECTOR: Vector quantities have both magnitudes and direction.

Explanation:

They are alike as they are both used to explain physical quantities and represent the magnitudes or sizes of the physical quantities...

They are different as VECTOR quantities describe an objects DIRECTION as well as magnitude whilst SCALAR doesn't

ie...<u>SCALAR:</u> MASS, TIME

<u>VECTOR:</u> VELOCITY, ACCELERATION...

I HOPE THIS HELPS!!

I would guess anything that is black? black absorbs there most light energy. that's is why a black car in the sun will always be hotter inside than a white car.

1. A car accelerates uniformly from 12 m/s to 39 m/s in 12 seconds. What is the car's average acceleration

Alinara [238K]

Answer:

(1) 2.25m/s^2

(2) 45.6m

Explanation:

(1) A car accelerates uniformly from 12m/s to 39m/s in 12 seconds

Therefore the average acceleration can be calculated as follows

a = 39-12/12

a = 27/12

a= 2.25m/s^2

(2) A butterfly is flying at 4m/s , it accelerates uniformly at 1.2 m/s for 6 seconds

u= 4

a= 1.2

t= 6

Therefore the distance can be calculated as follows

S= ut + 1/2at^2

= 4×6 + 1/2 × 1.2 × 6^2

= 24 + 1/2 × 1.2 × 36

= 24 + 1/2 × 43.2

= 24 + 21.6

S = 45.6m

Hence the butterfly travels at 45.6m

"A 2000 kg car drives around a circular exit ramp with a radius of 30 meters. The car drives all the way around the ramp in 10 s

aev [14]

The speed of the car is 18.8 m/s

Explanation:

The variables that represent the givens are:

m = 2000 kg (mass of the car)

r = 30 m (radius of the curve)

t = 10 s (time elapsed to cover the curve)

The unknown is the speed of the car, which is given by:

$v=\frac{d}{t}$

where d is the distance covered by the car during the time t.

Here the car covers a circular trajectory of radius r, so the distance covered is

$d=2\pi r=2\pi(30)=188m$

Therefore, the speed of the car is

$v=\frac{188}{10}=18.8 m/s$

A mass of 630g is hung on a spring. Using Force = mass x gravity, what is the force of the mass, acting on the spring?

hodyreva [135]

Answer:

6.174N or roughly 6.2N

Explanation:

630g=0.63kg

F=m*g=0.63*9.8=6.174N
