The global configuration command ip default-gateway 172. 16. 100. 1 is applied to a switch. What is the effect of this command?.
In order to sequence the dna barcoding region of your sample, a pcr reaction is performed to amplify the region of dna that will be sequenced. This reaction depends on the selection of the pcr primers. To predict the size of the pcr product with a specific primer pair, a virtual pcr can be performed using _________________.
the focal length of a converging lens is group of answer choices the distance at which parallel light rays are focused. the distance at which an object must be placed to form an image. the distance at which an image is formed. the distance from the front surface to the back surface.
a fully loaded, slow-moving freight elevator has a cab with a total mass of 1170 kg, which is required to travel upward 57 m in 3.3 min, starting and ending at rest. the elevator's counterweight has a mass of only 955 kg, and so the elevator motor must help. what average power is required of the force the motor exerts on the cab via the cable?
light from an object passes throug two lenses. the magnification of the image produced by the first lens is m1. this image acts as the object for the second lens, which produces an image of magnification m2. what is the overall magnification of the final image relative to the object?
an object is placed at 19.3 cm in front of a diverging lens with a focal length of -18.7 cm. what is the magnification? enter a number with 2 digits behind the decimal point.
suppose a disk rotates at constant angular velocity. (a) does a point on the rim have radial and/or tangential acceleration? explain. (b) if the disk's angular velocity increases uniformly, does the point have radial and/or tangential acceleration? (c) for what cases would the magnitude of either component of linear acceleration change? explain.
a record turntable is rotating at 33 rev/min. a watermelon seed is on the turntable 9.4 cm from the axis of rotation. (a) calculate the acceleration of the seed, assuming that it does not slip. (b) what is the minimum value of the coefficient of static friction between the seed and the turntable if the seed is not to slip? (c) suppose that the turntable achieves its angular speed by starting from rest and undergoing a constant angular acceleration for 0.23 s. calculate the minimum coefficient of static friction required for the seed not to slip during the acceleration period.
jupiter contains a number of small moons that are thought to be captured comets or material ejected by collisions with larger objects. what is the evidence for this theory? group of answer choices analyses from spacecraft show they have compositions completely different than jupiter or its moons. their orbits are highly elliptical, off the plane of the ecliptic, and many are retrograde, which is unlikely for satellite formed during planetary accretion. they are too big to have been formed during planetary accretion. spacecraft have sampled them, and they are known to be comets.
The mid-atlantic ridge formed at the edges of the north american and eurasian plates. Approximately, where does it start and end?.
a disk, initially rotating at 114 rad/s, is slowed down with a constant angular acceleration of magnitude 4.94 rad/s2. (a) how much time does the disk take to stop? (b) through what angle (rad) does the disk rotate during that time?
the electric field of an electromagnetic wave points in the positive y direction. at the same time, the magnetic field of this wave points in the positive z direction. in what direction is the wave traveling?
calculate the diameter of a copper conductor that is 1000 m long and has an internal resistance of 2.6 ohms. the resistivity of copper is 1.72x10-8. show your wor
if m1m1m 1 is 24 kilograms, m2m2m 2 is 12 kilograms, and mbarmbarm bar is 10 kilograms, what is the direction of rotation and the sign of the angular acceleration?
when the first solid bits in the solar nebula became large enough to be called planetesimals, what caused them to grow larger more quickly? group of answer choices
