Answer:
The weight of the probe is 50 Newtons
Explanation:
Newtons second law states that F = ma
Given the mass of 25kg, and the acceleration of 2m/s^2, we can substitute both values into the equation to find the weight force.
The weight of the probe is 50 Newtons
Answer:
2.10 V
Explanation:
To find the potential difference across the ends of the bar, you take into account that when the bar moves with speed v, in a constant magnetic field, the charges in the wire feels a magnetic force that separate the opposite charges, generating an induced potential difference given by the following formula:
(1)
v: speed of the bar = 11.5 m/s
B: magnitude of the magnetic field = 1.22 T
L: length of the bar = 15.0cm = 0.15m
You replace the values of v, B and L in the equation (1):
hence, the induced potential difference is 2.10 V
Answer:
Q1 acceleration = 16m/s²
Q2 Net force = 9N North
Explanation:
Q1 Using the formula F=ma
Q2 R = F1 + F2
Complete Question:
What force (in N) must be exerted on the master cylinder of a hydraulic lift to support the weight of a 2100 kg car (a large car) resting on the slave cylinder
? The master cylinder has a 2.00-cm diameter and the slave has a 24.0-cm diameter
Answer:
Explanation:
Given
--- mass
--- diameter of the large cylinder
--- diameter of the slave cylinder
To do this, we apply Archimedes' principle of buoyancy which implies that:
Where

Calculating the area of the master cylinder.
Calculating the area of the slave cylinder.
Substitute these values in:
Multiply both sides by
The force exerted on the slave cylinder (F2) is calculated as:
Substitute 20580 for F2 in
<em>Hence, the force exerted on the master cylinder is approximately 142.92N</em>
