The correct answer is “C” ultrasound. Hope this helps!
cause an object to accelerate in a direction opposite to the unbalanced force
Explanation:
An unbalanced force is defined as any force that causes an object to accelerate in a direction opposite to the unbalanced force.
The unbalanced force is the net or resultant force describe in newton's second law of motion.
In the first law, it is the external force that causes the motion of a body to change.
Unbalanced forces can cause body to either accelerate in the direction of the force or in an opposite direction of the force.

Answer:
w = 0.319 rad / s
Explanation:
This is an angular momentum problem, let's form a system composed of the feeder and the squirrel, therefore the forces during the collision are internal and the angular momentum is conserved.
initial instant. Before the squirrel jumps
L₀ = m v r
final instant. After the trough and the squirrel are together
L_f = (I_fetter + I_ardilla) w
angular momentum is conserved
L₀ = L_f
m v r = (I_fetter + I_ardilla) w
w =
the moment inercial ofbody is
I_thed = 2.00 kg m²
We approach the squirrel to a specific mass
I_ardilla = m r²
we substitute
w = m v r / ( I_[feefer + m r²)
let's calculate
w = 3 3.40 6.30 10⁻² / (2.00 + 3.00 (6.30 10-2)² )
w = 0.6426 / 2.0119
w = 0.319 rad / s
Answer:
The tension in the cord is 24.1 Newton
Explanation:
<u>Step 1:</u> Data given
mass of the ball = 1.13 kg
Cord = 0.50m
velocity = 2.4 m/s
<u>Step 2:</u> Calculate the tension
Fnet = F(c)
T - F(g) = F(c)
⇒ with F(g) = force of gravity = m*g
⇒ with F(C) = centripetal force = (mv²)/r
T = (mv²)/r + mg
⇒ with m = mass = 1.133 kg
⇒ with v = velocity = 2.4 m/s
⇒ with r = radius = 0.50 m
T = (1.13 * 2.4²) / 0.50 + 1.13 * 9.81
T = 24.1 Newton
The tension in the cord is 24.1 Newton
