Answer:

Velosity :

V = 3 m/s

Explanation:

Given:

m = 15 kg

F = 150 N

R = 90 cm = 0.90 m

________________

V - ?

Acceleration:

(1)  a = F / m

(2) a = V² / R

Equate (2) and (1):

V² / R = F / m

Velocity:

V = ​√ (F·R / m)

V = √ (150·0.90 / 15) = √ 9 = 3 m/s

Velocity of object experiencing a net force of 150N while traveling in a circle of radius 90cm is 3m/s.

To solve this problem concept of centripetal force can be applied.

Given that,

F=150N

r= 90cm

= 0.9m

m= 15kg

Substituting the given values in the formula of centripetal force:

F= m*v^2/r

150N = 15*v^2/0.9

v^2 = 150*0.9/ 15

v^2 = 9

v = √9

v= 3m/s

An object is travelling faster while it is rotating in a circle. Even when traveling at a constant speed around the circle's edge, there is a change in velocity, which leads to an acceleration. The circle's center is the target of this acceleration.

Furthermore, an item that experiences acceleration must also be subject to a net force, according to Newton's second law of motion. The acceleration is moving in the same direction as the net force. Therefore, for an object to accelerate inward while travelling in a circle, there must be an inner force acting on the object. The centripetal force is another name for this.

Anettt [7]

Answer:

It's centripetal acceleration is 301.7 m/s²

Explanation:

The formula to be used here is that of the centripetal acceleration which is

ac = rω²

where ac is the centripetal acceleration = ?

ω is the angular velocity = 3 revolutions per second is to be converted to radian per second: 3 × 2π  = 3 × 2 × 3.14 = 18.84 rad/s

r is the radius = 0.85 m

ac = 0.85 × 18.84²

ac = 301.7 m/s²

It's centripetal acceleration is 301.7 m/s²

irakobra [83]

Answer:

C. Sunlight to electricity

Explanation:

Photo voltaic cells covert sunlight to the electricity. It absorbs the light from the sun and use that sunlight to create electric current. The number of photo voltaic cells are connected together in a solar panel to generate enough electricity to power up a home.

constant force F=5i+5j−1kF=5i+5j−1k is applied to an object that is moving along a straight line from the point (−5,−3,−4)(−5,−3
meriva

Answer:

W = 71J

Explanation:

Given force F = (5i+5j−1k)N

d = Δr

r1 = (−5,−3,−4)m

r2 = (2,5,0)m

Δr = r2 – r1 = (2-(-5), 5-(-3), 0-(-4))

Δr = (2+5, 5+3, 0+4) = (7i+ 8j +4k)m

W = F•d = (5i+5j−1k)•(7i+ 8j +4k)

W = 5×7 + 5×8 +-1×4 = 35 + 40 - 4

W = 71J
