The net force in the tug of war which is shown in the picture provided will be 0N.

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

This is defined as the power exerted on a body and the unit of Force is referred to as Newton.

In the tug of war, the net force is gotten by summing up all the forces.

–190N + 10N –10N + 190N = 0N.

Therefore the net force is 0N.

castortr0y [4]

Answer:

A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.

Explanation:

A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.

Some of the names of the basic quantities include:

  1. Mass, denoted by the symbol 'm', with S.I. unit 'kg'
  2. Length, denoted by symbol 'l', with S.I. unit 'm'
  3. Time, denoted by symbol 't', with S.I. unit 's'
  4. Current, denoted by 'I', with S.I. unit 's' 'A'
  5. Temperature, denoted by 'T', with S.I. unit 'K'
  6. Amount of substance, denoted by 'n', with S.I. unit 'mol'
  7. Luminous Intensity, denoted by 'Iv', with S.I. unit 'cd'

  • A basic quantity is chosen arbitrarily.

3) A bird flies toward a tree limb at a 45-degree angle to the ground along a path that is 50 m long landing on the limb. Determ
marin [14]

Answer:

35 m

Explanation:

Given :

The distance of the path from the ground to the tree limb = 50 m

The angle between the path of flight of the bird towards the tree limb and the ground = 45 degrees

Therefore we can determine the height above which the bird perched above the ground by using the rules of the trigonometric ratios as;

We know that ,

$\sin 45^\circ =\frac{\text{perpendicular}}{\text{hypothenus}}$

$\sin 45^\circ =\frac{\text{BC}}{\text{AC}}$

$0.7  =\frac{\text{BC}}{\text{50}}$

\text{BC }= 0.7 \times 50

       = 35

Therefore, the bird perched on the tree limb at a height of 35 m.

Consider blood (density 1025 kg/m3) flowing through an artery with circular cross section that looks like this: Ignore viscosity
Klio2033 [76]

The given question is incomplete. The complete question is attached with an image below.

Explanation:

Mass flow rate through region A will be calculated as follows.

Rate = \rho \times A \times \mu

       = \rho \times \pi \times R^{2} \times \mu

       = 1025 \times 3.14 \times (0.5 \times 10^{-2})^{2} \times 30 \times 10^{-2}

       = 24138.75 \times 10^{6} kg/s

Therefore, we can conclude that the mass flow rate through region A is 24138.75 \times 10^{6} kg/s.

Please help me I really need it
tensa zangetsu [6.8K]

Answer:

A 1.5 metres per second squared B 0 C 6 0.5

b) 9m

Explanation:

a= v-a/t

a= acceleration measured in metres per second squared

v= final speed measured in metres per second

u= initial speed measured in metres per second

t= time measured in second

A

a=v-a/t

a= 3-0/2

a= 1.5 metres per second squared

Distance in a velocity time graph = area under

To calculate the distance in the first 4 seconds

You divide the graph into triangles and rectangles

Area A (triangle )= 1/2 × base × height

=1÷2 ×2×3

= 3m

Area B (rectangle)= L×B

=2×3

=6m

Area A + Area B= 3+6

= 9m
